+Description:
+		Perform SMBIOS calls on supported Dell machines.
+		through the Dell ACPI-WMI interface.
+
+		IOCTL's and buffer formats are defined in:
+		<uapi/linux/wmi.h>
+
+		1) To perform an SMBIOS call from userspace, you'll need to
+		first determine the minimum size of the calling interface
+		buffer for your machine.
+		Platforms that contain larger buffers can return larger
+		objects from the system firmware.
+		Commonly this size is either 4k or 32k.
+
+		To determine the size of the buffer read() a u64 dword from
+		the WMI character device /dev/wmi/dell-smbios.
+
+		2) After you've determined the minimum size of the calling
+		interface buffer, you can allocate a structure that represents
+		the structure documented above.
+
+		3) In the 'length' object store the size of the buffer you
+		determined above and allocated.
+
+		4) In this buffer object, prepare as necessary for the SMBIOS
+		call you're interested in.  Typically SMBIOS buffers have
+		"class", "select", and "input" defined to values that coincide
+		with the data you are interested in.
+		Documenting class/select/input values is outside of the scope
+		of this documentation. Check with the libsmbios project for
+		further documentation on these values.
+
+		6) Run the call by using ioctl() as described in the header.
+
+		7) The output will be returned in the buffer object.
+
+		8) Be sure to free up your allocated object.

 		HMAC-sha1 value across the extended attributes, storing the
 		value as the extended attribute 'security.evm'.
 
-		EVM depends on the Kernel Key Retention System to provide it
-		with a trusted/encrypted key for the HMAC-sha1 operation.
-		The key is loaded onto the root's keyring using keyctl.  Until
-		EVM receives notification that the key has been successfully
-		loaded onto the keyring (echo 1 > <securityfs>/evm), EVM
-		can not create or validate the 'security.evm' xattr, but
-		returns INTEGRITY_UNKNOWN.  Loading the key and signaling EVM
-		should be done as early as possible.  Normally this is done
-		in the initramfs, which has already been measured as part
-		of the trusted boot.  For more information on creating and
-		loading existing trusted/encrypted keys, refer to:
-		Documentation/keys-trusted-encrypted.txt.  (A sample dracut
-		patch, which loads the trusted/encrypted key and enables
-		EVM, is available from http://linux-ima.sourceforge.net/#EVM.)
+		EVM supports two classes of security.evm. The first is
+		an HMAC-sha1 generated locally with a
+		trusted/encrypted key stored in the Kernel Key
+		Retention System. The second is a digital signature
+		generated either locally or remotely using an
+		asymmetric key. These keys are loaded onto root's
+		keyring using keyctl, and EVM is then enabled by
+		echoing a value to <securityfs>/evm:
+
+		1: enable HMAC validation and creation
+		2: enable digital signature validation
+		3: enable HMAC and digital signature validation and HMAC
+		   creation
+
+		Further writes will be blocked if HMAC support is enabled or
+		if bit 32 is set:
+
+		echo 0x80000002 ><securityfs>/evm
+
+		will enable digital signature validation and block
+		further writes to <securityfs>/evm.
+
+		Until this is done, EVM can not create or validate the
+		'security.evm' xattr, but returns INTEGRITY_UNKNOWN.
+		Loading keys and signaling EVM should be done as early

+<h3><a name="What Is Tree RCU's Grace Period Memory Ordering Guarantee?">
+What Is Tree RCU's Grace Period Memory Ordering Guarantee?</a></h3>
+
+<p>RCU grace periods provide extremely strong memory-ordering guarantees
+for non-idle non-offline code.
+Any code that happens after the end of a given RCU grace period is guaranteed
+to see the effects of all accesses prior to the beginning of that grace
+period that are within RCU read-side critical sections.
+Similarly, any code that happens before the beginning of a given RCU grace
+period is guaranteed to see the effects of all accesses following the end
+of that grace period that are within RCU read-side critical sections.
+
+<p>This guarantee is particularly pervasive for <tt>synchronize_sched()</tt>,
+for which RCU-sched read-side critical sections include any region
+of code for which preemption is disabled.
+Given that each individual machine instruction can be thought of as
+an extremely small region of preemption-disabled code, one can think of
+<tt>synchronize_sched()</tt> as <tt>smp_mb()</tt> on steroids.
+
+<p>RCU updaters use this guarantee by splitting their updates into
+two phases, one of which is executed before the grace period and
+the other of which is executed after the grace period.
+In the most common use case, phase one removes an element from
+a linked RCU-protected data structure, and phase two frees that element.
+For this to work, any readers that have witnessed state prior to the
+phase-one update (in the common case, removal) must not witness state
+following the phase-two update (in the common case, freeing).
+
+<p>The RCU implementation provides this guarantee using a network
+of lock-based critical sections, memory barriers, and per-CPU
+processing, as is described in the following sections.
+
+<h3><a name="Tree RCU Grace Period Memory Ordering Building Blocks">
+Tree RCU Grace Period Memory Ordering Building Blocks</a></h3>
+
+<p>The workhorse for RCU's grace-period memory ordering is the
+critical section for the <tt>rcu_node</tt> structure's
+<tt>-&gt;lock</tt>.
+These critical sections use helper functions for lock acquisition, including
+<tt>raw_spin_lock_rcu_node()</tt>,
+<tt>raw_spin_lock_irq_rcu_node()</tt>, and
+<tt>raw_spin_lock_irqsave_rcu_node()</tt>.
+Their lock-release counterparts are
+<tt>raw_spin_unlock_rcu_node()</tt>,
+<tt>raw_spin_unlock_irq_rcu_node()</tt>, and
+<tt>raw_spin_unlock_irqrestore_rcu_node()</tt>,
+respectively.
+For completeness, a
+<tt>raw_spin_trylock_rcu_node()</tt>
+is also provided.
+The key point is that the lock-acquisition functions, including
+<tt>raw_spin_trylock_rcu_node()</tt>, all invoke
+<tt>smp_mb__after_unlock_lock()</tt> immediately after successful
+acquisition of the lock.
+
+<p>Therefore, for any given <tt>rcu_node</tt> struction, any access
+happening before one of the above lock-release functions will be seen
+by all CPUs as happening before any access happening after a later
+one of the above lock-acquisition functions.
+Furthermore, any access happening before one of the
+above lock-release function on any given CPU will be seen by all
+CPUs as happening before any access happening after a later one
+of the above lock-acquisition functions executing on that same CPU,
+even if the lock-release and lock-acquisition functions are operating
+on different <tt>rcu_node</tt> structures.
+Tree RCU uses these two ordering guarantees to form an ordering
+network among all CPUs that were in any way involved in the grace
+period, including any CPUs that came online or went offline during
+the grace period in question.
+
+<p>The following litmus test exhibits the ordering effects of these
+lock-acquisition and lock-release functions:
+
+<pre>
+ 1 int x, y, z;
+ 2
+ 3 void task0(void)
+ 4 {
+ 5   raw_spin_lock_rcu_node(rnp);
+ 6   WRITE_ONCE(x, 1);
+ 7   r1 = READ_ONCE(y);
+ 8   raw_spin_unlock_rcu_node(rnp);
+ 9 }
+10
+11 void task1(void)
+12 {
+13   raw_spin_lock_rcu_node(rnp);
+14   WRITE_ONCE(y, 1);
+15   r2 = READ_ONCE(z);
+16   raw_spin_unlock_rcu_node(rnp);
+17 }
+18
+19 void task2(void)
+20 {
+21   WRITE_ONCE(z, 1);
+22   smp_mb();
+23   r3 = READ_ONCE(x);
+24 }
+25
+26 WARN_ON(r1 == 0 &amp;&amp; r2 == 0 &amp;&amp; r3 == 0);
+</pre>
+
+<p>The <tt>WARN_ON()</tt> is evaluated at &ldquo;the end of time&rdquo;,
+after all changes have propagated throughout the system.
+Without the <tt>smp_mb__after_unlock_lock()</tt> provided by the
+acquisition functions, this <tt>WARN_ON()</tt> could trigger, for example
+on PowerPC.
+The <tt>smp_mb__after_unlock_lock()</tt> invocations prevent this
+<tt>WARN_ON()</tt> from triggering.
+
+<p>This approach must be extended to include idle CPUs, which need
+RCU's grace-period memory ordering guarantee to extend to any
+RCU read-side critical sections preceding and following the current
+idle sojourn.
+This case is handled by calls to the strongly ordered
+<tt>atomic_add_return()</tt> read-modify-write atomic operation that
+is invoked within <tt>rcu_dynticks_eqs_enter()</tt> at idle-entry
+time and within <tt>rcu_dynticks_eqs_exit()</tt> at idle-exit time.
+The grace-period kthread invokes <tt>rcu_dynticks_snap()</tt> and
+<tt>rcu_dynticks_in_eqs_since()</tt> (both of which invoke
+an <tt>atomic_add_return()</tt> of zero) to detect idle CPUs.

+<p>Tree RCU's grace--period memory-ordering guarantees rely most
+heavily on the <tt>rcu_node</tt> structure's <tt>-&gt;lock</tt>
+field, so much so that it is necessary to abbreviate this pattern
+in the diagrams in the next section.
+For example, consider the <tt>rcu_prepare_for_idle()</tt> function
+shown below, which is one of several functions that enforce ordering
+of newly arrived RCU callbacks against future grace periods:
+
+<pre>
+ 1 static void rcu_prepare_for_idle(void)

+24     rdtp-&gt;all_lazy = false;
+25     rdtp-&gt;nonlazy_posted_snap = rdtp-&gt;nonlazy_posted;
+26     invoke_rcu_core();
+27     return;
+28   }
+29   if (rdtp-&gt;last_accelerate == jiffies)
+30     return;
+31   rdtp-&gt;last_accelerate = jiffies;

+
+<h4><a name="Callback Registry">Callback Registry</a></h4>
+
+<p>If RCU's grace-period guarantee is to mean anything at all, any
+access that happens before a given invocation of <tt>call_rcu()</tt>
+must also happen before the corresponding grace period.
+The implementation of this portion of RCU's grace period guarantee
+is shown in the following figure:
+
+</p><p><img src="TreeRCU-callback-registry.svg" alt="TreeRCU-callback-registry.svg">
+
+<p>Because <tt>call_rcu()</tt> normally acts only on CPU-local state,
+it provides no ordering guarantees, either for itself or for
+phase one of the update (which again will usually be removal of
+an element from an RCU-protected data structure).
+It simply enqueues the <tt>rcu_head</tt> structure on a per-CPU list,
+which cannot become associated with a grace period until a later
+call to <tt>rcu_accelerate_cbs()</tt>, as shown in the diagram above.
+
+<p>One set of code paths shown on the left invokes
+<tt>rcu_accelerate_cbs()</tt> via
+<tt>note_gp_changes()</tt>, either directly from <tt>call_rcu()</tt> (if
+the current CPU is inundated with queued <tt>rcu_head</tt> structures)
+or more likely from an <tt>RCU_SOFTIRQ</tt> handler.
+Another code path in the middle is taken only in kernels built with
+<tt>CONFIG_RCU_FAST_NO_HZ=y</tt>, which invokes
+<tt>rcu_accelerate_cbs()</tt> via <tt>rcu_prepare_for_idle()</tt>.
+The final code path on the right is taken only in kernels built with
+<tt>CONFIG_HOTPLUG_CPU=y</tt>, which invokes
+<tt>rcu_accelerate_cbs()</tt> via
+<tt>rcu_advance_cbs()</tt>, <tt>rcu_migrate_callbacks</tt>,
+<tt>rcutree_migrate_callbacks()</tt>, and <tt>takedown_cpu()</tt>,
+which in turn is invoked on a surviving CPU after the outgoing
+CPU has been completely offlined.
+
+<p>There are a few other code paths within grace-period processing
+that opportunistically invoke <tt>rcu_accelerate_cbs()</tt>.
+However, either way, all of the CPU's recently queued <tt>rcu_head</tt>
+structures are associated with a future grace-period number under
+the protection of the CPU's lead <tt>rcu_node</tt> structure's
+<tt>-&gt;lock</tt>.
+In all cases, there is full ordering against any prior critical section
+for that same <tt>rcu_node</tt> structure's <tt>-&gt;lock</tt>, and
+also full ordering against any of the current task's or CPU's prior critical
+sections for any <tt>rcu_node</tt> structure's <tt>-&gt;lock</tt>.
+
+<p>The next section will show how this ordering ensures that any
+accesses prior to the <tt>call_rcu()</tt> (particularly including phase
+one of the update)
+happen before the start of the corresponding grace period.

+<h4><a name="Grace-Period Initialization">Grace-Period Initialization</a></h4>
+
+<p>Grace-period initialization is carried out by
+the grace-period kernel thread, which makes several passes over the
+<tt>rcu_node</tt> tree within the <tt>rcu_gp_init()</tt> function.
+This means that showing the full flow of ordering through the
+grace-period computation will require duplicating this tree.
+If you find this confusing, please note that the state of the
+<tt>rcu_node</tt> changes over time, just like Heraclitus's river.
+However, to keep the <tt>rcu_node</tt> river tractable, the
+grace-period kernel thread's traversals are presented in multiple
+parts, starting in this section with the various phases of
+grace-period initialization.
+
+<p>The first ordering-related grace-period initialization action is to
+increment the <tt>rcu_state</tt> structure's <tt>-&gt;gpnum</tt>
+grace-period-number counter, as shown below:
+
+</p><p><img src="TreeRCU-gp-init-1.svg" alt="TreeRCU-gp-init-1.svg" width="75%">
+
+<p>The actual increment is carried out using <tt>smp_store_release()</tt>,
+which helps reject false-positive RCU CPU stall detection.
+Note that only the root <tt>rcu_node</tt> structure is touched.
+
+<p>The first pass through the <tt>rcu_node</tt> tree updates bitmasks
+based on CPUs having come online or gone offline since the start of
+the previous grace period.
+In the common case where the number of online CPUs for this <tt>rcu_node</tt>
+structure has not transitioned to or from zero,
+this pass will scan only the leaf <tt>rcu_node</tt> structures.
+However, if the number of online CPUs for a given leaf <tt>rcu_node</tt>
+structure has transitioned from zero,
+<tt>rcu_init_new_rnp()</tt> will be invoked for the first incoming CPU.
+Similarly, if the number of online CPUs for a given leaf <tt>rcu_node</tt>
+structure has transitioned to zero,
+<tt>rcu_cleanup_dead_rnp()</tt> will be invoked for the last outgoing CPU.
+The diagram below shows the path of ordering if the leftmost
+<tt>rcu_node</tt> structure onlines its first CPU and if the next
+<tt>rcu_node</tt> structure has no online CPUs
+(or, alternatively if the leftmost <tt>rcu_node</tt> structure offlines
+its last CPU and if the next <tt>rcu_node</tt> structure has no online CPUs).
+
+</p><p><img src="TreeRCU-gp-init-2.svg" alt="TreeRCU-gp-init-1.svg" width="75%">
+
+<p>The final <tt>rcu_gp_init()</tt> pass through the <tt>rcu_node</tt>
+tree traverses breadth-first, setting each <tt>rcu_node</tt> structure's
+<tt>-&gt;gpnum</tt> field to the newly incremented value from the
+<tt>rcu_state</tt> structure, as shown in the following diagram.
+
+</p><p><img src="TreeRCU-gp-init-3.svg" alt="TreeRCU-gp-init-1.svg" width="75%">
+
+<p>This change will also cause each CPU's next call to
+<tt>__note_gp_changes()</tt>
+to notice that a new grace period has started, as described in the next
+section.
+But because the grace-period kthread started the grace period at the
+root (with the increment of the <tt>rcu_state</tt> structure's
+<tt>-&gt;gpnum</tt> field) before setting each leaf <tt>rcu_node</tt>
+structure's <tt>-&gt;gpnum</tt> field, each CPU's observation of
+the start of the grace period will happen after the actual start
+of the grace period.

+
+<p>This is for the last CPU to report a quiescent state, which signals

+Earlier quiescent states would push up the <tt>rcu_node</tt> tree

+However, ordering is nevertheless preserved because some later quiescent

+<p>If the CPU does a context switch, a quiescent state will be

+On the other hand, if the CPU takes a scheduler-clock interrupt
+while executing in usermode, a quiescent state will be noted by
+<tt>rcu_check_callbacks()</tt> on the right.
+Either way, the passage through a quiescent state will be noted

+
+<p>The next time an <tt>RCU_SOFTIRQ</tt> handler executes on

+recorded quiescent state, and invoke
+<tt>rcu_report_qs_rdp()</tt>.
+If <tt>rcu_report_qs_rdp()</tt> verifies that the quiescent state
+really does apply to the current grace period, it invokes
+<tt>rcu_report_rnp()</tt> which traverses up the <tt>rcu_node</tt>
+tree as shown at the bottom of the diagram, clearing bits from
+each <tt>rcu_node</tt> structure's <tt>-&gt;qsmask</tt> field,
+and propagating up the tree when the result is zero.
+
+<p>Note that traversal passes upwards out of a given <tt>rcu_node</tt>
+structure only if the current CPU is reporting the last quiescent
+state for the subtree headed by that <tt>rcu_node</tt> structure.
+A key point is that if a CPU's traversal stops at a given <tt>rcu_node</tt>
+structure, then there will be a later traversal by another CPU
+(or perhaps the same one) that proceeds upwards
+from that point, and the <tt>rcu_node</tt> <tt>-&gt;lock</tt>
+guarantees that the first CPU's quiescent state happens before the
+remainder of the second CPU's traversal.
+Applying this line of thought repeatedly shows that all CPUs'
+quiescent states happen before the last CPU traverses through
+the root <tt>rcu_node</tt> structure, the &ldquo;last CPU&rdquo;

+<p>Due to energy-efficiency considerations, RCU is forbidden from

+CPUs are therefore required to notify RCU when entering or leaving idle
+state, which they do via fully ordered value-returning atomic operations
+on a per-CPU variable.
+The ordering effects are as shown below:

+This means that any RCU read-side critical sections that precede the
+idle period (the oval near the top of the diagram above) will happen
+before the end of the current grace period.
+Similarly, the beginning of the current grace period will happen before
+any RCU read-side critical sections that follow the

+<h4><a name="CPU-Hotplug Interface">CPU-Hotplug Interface</a></h4>
+
+<p>RCU is also forbidden from disturbing offline CPUs, which might well

+CPUs are therefore required to notify RCU of their comings and goings
+as part of the corresponding CPU hotplug operations.
+The ordering effects are shown below:
+
+</p><p><img src="TreeRCU-hotplug.svg" alt="TreeRCU-hotplug.svg" width="50%">
+
+<p>Because CPU hotplug operations are much less frequent than idle transitions,
+they are heavier weight, and thus acquire the CPU's leaf <tt>rcu_node</tt>
+structure's <tt>-&gt;lock</tt> and update this structure's
+<tt>-&gt;qsmaskinitnext</tt>.
+The RCU grace-period kernel thread samples this mask to detect CPUs
+having gone offline since the beginning of this grace period.

+
+<h4><a name="Forcing Quiescent States">Forcing Quiescent States</a></h4>
+
+<p>As noted above, idle and offline CPUs cannot report their own
+quiescent states, and therefore the grace-period kernel thread
+must do the reporting on their behalf.
+This process is called &ldquo;forcing quiescent states&rdquo;, it is
+repeated every few jiffies, and its ordering effects are shown below:

+leaf <tt>rcu_node</tt> structures, and if there are no new quiescent
+states due to recently idled and/or offlined CPUs, then only the
+leaves are traversed.
+However, if there is a newly offlined CPU as illustrated on the left
+or a newly idled CPU as illustrated on the right, the corresponding
+quiescent state will be driven up towards the root.
+As with self-reported quiescent states, the upwards driving stops

+<h4><a name="Callback Invocation">Callback Invocation</a></h4>
+
+<p>Once a given CPU's leaf <tt>rcu_node</tt> structure's
+<tt>-&gt;completed</tt> field has been updated, that CPU can begin
+invoking its RCU callbacks that were waiting for this grace period
+to end.
+These callbacks are identified by <tt>rcu_advance_cbs()</tt>,
+which is usually invoked by <tt>__note_gp_changes()</tt>.
+As shown in the diagram below, this invocation can be triggered by
+the scheduling-clock interrupt (<tt>rcu_check_callbacks()</tt> on
+the left) or by idle entry (<tt>rcu_cleanup_after_idle()</tt> on
+the right, but only for kernels build with
+<tt>CONFIG_RCU_FAST_NO_HZ=y</tt>).
+Either way, <tt>RCU_SOFTIRQ</tt> is raised, which results in
+<tt>rcu_do_batch()</tt> invoking the callbacks, which in turn
+allows those callbacks to carry out (either directly or indirectly
+via wakeup) the needed phase-two processing for each update.
+
+</p><p><img src="TreeRCU-callback-invocation.svg" alt="TreeRCU-callback-invocation.svg" width="60%">
+
+<p>Please note that callback invocation can also be prompted by any
+number of corner-case code paths, for example, when a CPU notes that
+it has excessive numbers of callbacks queued.
+In all cases, the CPU acquires its leaf <tt>rcu_node</tt> structure's
+<tt>-&gt;lock</tt> before invoking callbacks, which preserves the
+required ordering against the newly completed grace period.
+
+<p>However, if the callback function communicates to other CPUs,
+for example, doing a wakeup, then it is that function's responsibility
+to maintain ordering.
+For example, if the callback function wakes up a task that runs on
+some other CPU, proper ordering must in place in both the callback
+function and the task being awakened.
+To see why this is important, consider the top half of the
+<a href="#Grace-Period Cleanup">grace-period cleanup</a> diagram.
+The callback might be running on a CPU corresponding to the leftmost
+leaf <tt>rcu_node</tt> structure, and awaken a task that is to run on
+a CPU corresponding to the rightmost leaf <tt>rcu_node</tt> structure,
+and the grace-period kernel thread might not yet have reached the
+rightmost leaf.
+In this case, the grace period's memory ordering might not yet have
+reached that CPU, so again the callback function and the awakened
+task must supply proper ordering.

+Networking over Thunderbolt cable
+---------------------------------
+Thunderbolt technology allows software communication across two hosts
+connected by a Thunderbolt cable.
+
+It is possible to tunnel any kind of traffic over Thunderbolt link but
+currently we only support Apple ThunderboltIP protocol.
+
+If the other host is running Windows or macOS only thing you need to
+do is to connect Thunderbolt cable between the two hosts, the
+``thunderbolt-net`` is loaded automatically. If the other host is also
+Linux you should load ``thunderbolt-net`` manually on one host (it does
+not matter which one)::
+
+  # modprobe thunderbolt-net
+
+This triggers module load on the other host automatically. If the driver
+is built-in to the kernel image, there is no need to do anything.
+
+The driver will create one virtual ethernet interface per Thunderbolt
+port which are named like ``thunderbolt0`` and so on. From this point
+you can either use standard userspace tools like ``ifconfig`` to
+configure the interface or let your GUI to handle it automatically.
+
+Forcing power
+-------------
+Many OEMs include a method that can be used to force the power of a
+thunderbolt controller to an "On" state even if nothing is connected.
+If supported by your machine this will be exposed by the WMI bus with
+a sysfs attribute called "force_power".
+
+For example the intel-wmi-thunderbolt driver exposes this attribute in:
+  /sys/devices/platform/PNP0C14:00/wmi_bus/wmi_bus-PNP0C14:00/86CCFD48-205E-4A77-9C48-2021CBEDE341/force_power
+
+  To force the power to on, write 1 to this attribute file.
+  To disable force power, write 0 to this attribute file.
+
+Note: it's currently not possible to query the force power state of a platform.

+ARM64 ELF hwcaps
+================
+
+This document describes the usage and semantics of the arm64 ELF hwcaps.
+
+
+1. Introduction
+---------------
+
+Some hardware or software features are only available on some CPU
+implementations, and/or with certain kernel configurations, but have no
+architected discovery mechanism available to userspace code at EL0. The
+kernel exposes the presence of these features to userspace through a set
+of flags called hwcaps, exposed in the auxilliary vector.
+
+Userspace software can test for features by acquiring the AT_HWCAP entry
+of the auxilliary vector, and testing whether the relevant flags are
+set, e.g.
+
+bool floating_point_is_present(void)
+{
+	unsigned long hwcaps = getauxval(AT_HWCAP);
+	if (hwcaps & HWCAP_FP)
+		return true;
+
+	return false;
+}
+
+Where software relies on a feature described by a hwcap, it should check
+the relevant hwcap flag to verify that the feature is present before
+attempting to make use of the feature.
+
+Features cannot be probed reliably through other means. When a feature
+is not available, attempting to use it may result in unpredictable
+behaviour, and is not guaranteed to result in any reliable indication
+that the feature is unavailable, such as a SIGILL.
+
+
+2. Interpretation of hwcaps
+---------------------------
+
+The majority of hwcaps are intended to indicate the presence of features
+which are described by architected ID registers inaccessible to
+userspace code at EL0. These hwcaps are defined in terms of ID register
+fields, and should be interpreted with reference to the definition of
+these fields in the ARM Architecture Reference Manual (ARM ARM).
+
+Such hwcaps are described below in the form:
+
+    Functionality implied by idreg.field == val.
+
+Such hwcaps indicate the availability of functionality that the ARM ARM
+defines as being present when idreg.field has value val, but do not
+indicate that idreg.field is precisely equal to val, nor do they
+indicate the absence of functionality implied by other values of
+idreg.field.
+
+Other hwcaps may indicate the presence of features which cannot be
+described by ID registers alone. These may be described without
+reference to ID registers, and may refer to other documentation.
+
+

+            Scalable Vector Extension support for AArch64 Linux
+            ===================================================
+
+Author: Dave Martin <Dave.Martin@arm.com>
+Date:   4 August 2017
+
+This document outlines briefly the interface provided to userspace by Linux in
+order to support use of the ARM Scalable Vector Extension (SVE).
+
+This is an outline of the most important features and issues only and not
+intended to be exhaustive.
+
+This document does not aim to describe the SVE architecture or programmer's
+model.  To aid understanding, a minimal description of relevant programmer's
+model features for SVE is included in Appendix A.
+
+
+1.  General
+-----------
+
+* SVE registers Z0..Z31, P0..P15 and FFR and the current vector length VL, are
+  tracked per-thread.
+
+* The presence of SVE is reported to userspace via HWCAP_SVE in the aux vector
+  AT_HWCAP entry.  Presence of this flag implies the presence of the SVE
+  instructions and registers, and the Linux-specific system interfaces
+  described in this document.  SVE is reported in /proc/cpuinfo as "sve".
+
+* Support for the execution of SVE instructions in userspace can also be
+  detected by reading the CPU ID register ID_AA64PFR0_EL1 using an MRS
+  instruction, and checking that the value of the SVE field is nonzero. [3]
+
+  It does not guarantee the presence of the system interfaces described in the
+  following sections: software that needs to verify that those interfaces are
+  present must check for HWCAP_SVE instead.
+
+* Debuggers should restrict themselves to interacting with the target via the
+  NT_ARM_SVE regset.  The recommended way of detecting support for this regset
+  is to connect to a target process first and then attempt a
+  ptrace(PTRACE_GETREGSET, pid, NT_ARM_SVE, &iov).
+
+
+2.  Vector length terminology
+-----------------------------
+
+The size of an SVE vector (Z) register is referred to as the "vector length".
+
+To avoid confusion about the units used to express vector length, the kernel
+adopts the following conventions:
+
+* Vector length (VL) = size of a Z-register in bytes
+
+* Vector quadwords (VQ) = size of a Z-register in units of 128 bits
+
+(So, VL = 16 * VQ.)
+
+The VQ convention is used where the underlying granularity is important, such
+as in data structure definitions.  In most other situations, the VL convention
+is used.  This is consistent with the meaning of the "VL" pseudo-register in
+the SVE instruction set architecture.
+
+
+3.  System call behaviour
+-------------------------
+
+* On syscall, V0..V31 are preserved (as without SVE).  Thus, bits [127:0] of
+  Z0..Z31 are preserved.  All other bits of Z0..Z31, and all of P0..P15 and FFR
+  become unspecified on return from a syscall.
+
+* The SVE registers are not used to pass arguments to or receive results from
+  any syscall.
+
+* In practice the affected registers/bits will be preserved or will be replaced
+  with zeros on return from a syscall, but userspace should not make
+  assumptions about this.  The kernel behaviour may vary on a case-by-case
+  basis.
+
+* All other SVE state of a thread, including the currently configured vector
+  length, the state of the PR_SVE_VL_INHERIT flag, and the deferred vector
+  length (if any), is preserved across all syscalls, subject to the specific
+  exceptions for execve() described in section 6.
+
+  In particular, on return from a fork() or clone(), the parent and new child
+  process or thread share identical SVE configuration, matching that of the
+  parent before the call.
+
+
+4.  Signal handling
+-------------------
+
+* A new signal frame record sve_context encodes the SVE registers on signal
+  delivery. [1]
+
+* This record is supplementary to fpsimd_context.  The FPSR and FPCR registers
+  are only present in fpsimd_context.  For convenience, the content of V0..V31
+  is duplicated between sve_context and fpsimd_context.
+
+* The signal frame record for SVE always contains basic metadata, in particular
+  the thread's vector length (in sve_context.vl).
+
+* The SVE registers may or may not be included in the record, depending on
+  whether the registers are live for the thread.  The registers are present if
+  and only if:
+  sve_context.head.size >= SVE_SIG_CONTEXT_SIZE(sve_vq_from_vl(sve_context.vl)).
+
+* If the registers are present, the remainder of the record has a vl-dependent
+  size and layout.  Macros SVE_SIG_* are defined [1] to facilitate access to
+  the members.
+
+* If the SVE context is too big to fit in sigcontext.__reserved[], then extra
+  space is allocated on the stack, an extra_context record is written in
+  __reserved[] referencing this space.  sve_context is then written in the
+  extra space.  Refer to [1] for further details about this mechanism.
+
+
+5.  Signal return
+-----------------
+
+When returning from a signal handler:
+
+* If there is no sve_context record in the signal frame, or if the record is
+  present but contains no register data as desribed in the previous section,
+  then the SVE registers/bits become non-live and take unspecified values.
+
+* If sve_context is present in the signal frame and contains full register
+  data, the SVE registers become live and are populated with the specified
+  data.  However, for backward compatibility reasons, bits [127:0] of Z0..Z31
+  are always restored from the corresponding members of fpsimd_context.vregs[]
+  and not from sve_context.  The remaining bits are restored from sve_context.
+
+* Inclusion of fpsimd_context in the signal frame remains mandatory,
+  irrespective of whether sve_context is present or not.
+
+* The vector length cannot be changed via signal return.  If sve_context.vl in
+  the signal frame does not match the current vector length, the signal return
+  attempt is treated as illegal, resulting in a forced SIGSEGV.
+
+
+6.  prctl extensions
+--------------------
+
+Some new prctl() calls are added to allow programs to manage the SVE vector
+length:
+
+prctl(PR_SVE_SET_VL, unsigned long arg)
+
+    Sets the vector length of the calling thread and related flags, where
+    arg == vl | flags.  Other threads of the calling process are unaffected.
+
+    vl is the desired vector length, where sve_vl_valid(vl) must be true.
+
+    flags:
+
+	PR_SVE_SET_VL_INHERIT
+
+	    Inherit the current vector length across execve().  Otherwise, the
+	    vector length is reset to the system default at execve().  (See
+	    Section 9.)
+
+	PR_SVE_SET_VL_ONEXEC
+
+	    Defer the requested vector length change until the next execve()
+	    performed by this thread.
+
+	    The effect is equivalent to implicit exceution of the following
+	    call immediately after the next execve() (if any) by the thread:
+
+		prctl(PR_SVE_SET_VL, arg & ~PR_SVE_SET_VL_ONEXEC)
+
+	    This allows launching of a new program with a different vector
+	    length, while avoiding runtime side effects in the caller.
+
+
+	    Without PR_SVE_SET_VL_ONEXEC, the requested change takes effect
+	    immediately.
+
+
+    Return value: a nonnegative on success, or a negative value on error:
+	EINVAL: SVE not supported, invalid vector length requested, or
+	    invalid flags.
+
+
+    On success:
+
+    * Either the calling thread's vector length or the deferred vector length
+      to be applied at the next execve() by the thread (dependent on whether
+      PR_SVE_SET_VL_ONEXEC is present in arg), is set to the largest value
+      supported by the system that is less than or equal to vl.  If vl ==
+      SVE_VL_MAX, the value set will be the largest value supported by the
+      system.
+
+    * Any previously outstanding deferred vector length change in the calling
+      thread is cancelled.
+
+    * The returned value describes the resulting configuration, encoded as for
+      PR_SVE_GET_VL.  The vector length reported in this value is the new
+      current vector length for this thread if PR_SVE_SET_VL_ONEXEC was not
+      present in arg; otherwise, the reported vector length is the deferred
+      vector length that will be applied at the next execve() by the calling
+      thread.
+
+    * Changing the vector length causes all of P0..P15, FFR and all bits of
+      Z0..V31 except for Z0 bits [127:0] .. Z31 bits [127:0] to become
+      unspecified.  Calling PR_SVE_SET_VL with vl equal to the thread's current
+      vector length, or calling PR_SVE_SET_VL with the PR_SVE_SET_VL_ONEXEC
+      flag, does not constitute a change to the vector length for this purpose.
+
+
+prctl(PR_SVE_GET_VL)
+
+    Gets the vector length of the calling thread.
+
+    The following flag may be OR-ed into the result:
+
+	PR_SVE_SET_VL_INHERIT
+
+	    Vector length will be inherited across execve().
+
+    There is no way to determine whether there is an outstanding deferred
+    vector length change (which would only normally be the case between a
+    fork() or vfork() and the corresponding execve() in typical use).
+
+    To extract the vector length from the result, and it with
+    PR_SVE_VL_LEN_MASK.
+
+    Return value: a nonnegative value on success, or a negative value on error:
+	EINVAL: SVE not supported.
+
+
+7.  ptrace extensions
+---------------------
+
+* A new regset NT_ARM_SVE is defined for use with PTRACE_GETREGSET and
+  PTRACE_SETREGSET.
+
+  Refer to [2] for definitions.
+
+The regset data starts with struct user_sve_header, containing:
+
+    size
+
+	Size of the complete regset, in bytes.
+	This depends on vl and possibly on other things in the future.
+
+	If a call to PTRACE_GETREGSET requests less data than the value of
+	size, the caller can allocate a larger buffer and retry in order to
+	read the complete regset.
+
+    max_size
+
+	Maximum size in bytes that the regset can grow to for the target
+	thread.  The regset won't grow bigger than this even if the target
+	thread changes its vector length etc.
+
+    vl
+
+	Target thread's current vector length, in bytes.
+
+    max_vl
+
+	Maximum possible vector length for the target thread.
+
+    flags
+
+	either
+
+	    SVE_PT_REGS_FPSIMD
+
+		SVE registers are not live (GETREGSET) or are to be made
+		non-live (SETREGSET).
+
+		The payload is of type struct user_fpsimd_state, with the same
+		meaning as for NT_PRFPREG, starting at offset
+		SVE_PT_FPSIMD_OFFSET from the start of user_sve_header.
+
+		Extra data might be appended in the future: the size of the
+		payload should be obtained using SVE_PT_FPSIMD_SIZE(vq, flags).
+
+		vq should be obtained using sve_vq_from_vl(vl).
+
+		or
+
+	    SVE_PT_REGS_SVE
+
+		SVE registers are live (GETREGSET) or are to be made live
+		(SETREGSET).
+
+		The payload contains the SVE register data, starting at offset
+		SVE_PT_SVE_OFFSET from the start of user_sve_header, and with
+		size SVE_PT_SVE_SIZE(vq, flags);
+
+	... OR-ed with zero or more of the following flags, which have the same
+	meaning and behaviour as the corresponding PR_SET_VL_* flags:
+
+	    SVE_PT_VL_INHERIT
+
+	    SVE_PT_VL_ONEXEC (SETREGSET only).
+
+* The effects of changing the vector length and/or flags are equivalent to
+  those documented for PR_SVE_SET_VL.
+
+  The caller must make a further GETREGSET call if it needs to know what VL is
+  actually set by SETREGSET, unless is it known in advance that the requested
+  VL is supported.
+
+* In the SVE_PT_REGS_SVE case, the size and layout of the payload depends on
+  the header fields.  The SVE_PT_SVE_*() macros are provided to facilitate
+  access to the members.
+
+* In either case, for SETREGSET it is permissible to omit the payload, in which
+  case only the vector length and flags are changed (along with any
+  consequences of those changes).
+
+* For SETREGSET, if an SVE_PT_REGS_SVE payload is present and the
+  requested VL is not supported, the effect will be the same as if the
+  payload were omitted, except that an EIO error is reported.  No
+  attempt is made to translate the payload data to the correct layout
+  for the vector length actually set.  The thread's FPSIMD state is
+  preserved, but the remaining bits of the SVE registers become
+  unspecified.  It is up to the caller to translate the payload layout
+  for the actual VL and retry.
+
+* The effect of writing a partial, incomplete payload is unspecified.
+
+
+8.  ELF coredump extensions
+---------------------------
+
+* A NT_ARM_SVE note will be added to each coredump for each thread of the
+  dumped process.  The contents will be equivalent to the data that would have
+  been read if a PTRACE_GETREGSET of NT_ARM_SVE were executed for each thread
+  when the coredump was generated.
+
+
+9.  System runtime configuration
+--------------------------------
+
+* To mitigate the ABI impact of expansion of the signal frame, a policy
+  mechanism is provided for administrators, distro maintainers and developers
+  to set the default vector length for userspace processes:
+
+/proc/sys/abi/sve_default_vector_length
+
+    Writing the text representation of an integer to this file sets the system
+    default vector length to the specified value, unless the value is greater
+    than the maximum vector length supported by the system in which case the
+    default vector length is set to that maximum.
+
+    The result can be determined by reopening the file and reading its
+    contents.
+
+    At boot, the default vector length is initially set to 64 or the maximum
+    supported vector length, whichever is smaller.  This determines the initial
+    vector length of the init process (PID 1).
+
+    Reading this file returns the current system default vector length.
+
+* At every execve() call, the new vector length of the new process is set to
+  the system default vector length, unless
+
+    * PR_SVE_SET_VL_INHERIT (or equivalently SVE_PT_VL_INHERIT) is set for the
+      calling thread, or
+
+    * a deferred vector length change is pending, established via the
+      PR_SVE_SET_VL_ONEXEC flag (or SVE_PT_VL_ONEXEC).
+
+* Modifying the system default vector length does not affect the vector length
+  of any existing process or thread that does not make an execve() call.
+
+
+Appendix A.  SVE programmer's model (informative)
+=================================================
+
+This section provides a minimal description of the additions made by SVE to the
+ARMv8-A programmer's model that are relevant to this document.
+
+Note: This section is for information only and not intended to be complete or
+to replace any architectural specification.
+
+A.1.  Registers
+---------------
+
+In A64 state, SVE adds the following:
+
+* 32 8VL-bit vector registers Z0..Z31
+  For each Zn, Zn bits [127:0] alias the ARMv8-A vector register Vn.
+
+  A register write using a Vn register name zeros all bits of the corresponding
+  Zn except for bits [127:0].
+
+* 16 VL-bit predicate registers P0..P15
+
+* 1 VL-bit special-purpose predicate register FFR (the "first-fault register")
+
+* a VL "pseudo-register" that determines the size of each vector register
+
+  The SVE instruction set architecture provides no way to write VL directly.
+  Instead, it can be modified only by EL1 and above, by writing appropriate
+  system registers.
+
+* The value of VL can be configured at runtime by EL1 and above:
+  16 <= VL <= VLmax, where VL must be a multiple of 16.
+
+* The maximum vector length is determined by the hardware:
+  16 <= VLmax <= 256.
+
+  (The SVE architecture specifies 256, but permits future architecture
+  revisions to raise this limit.)
+
+* FPSR and FPCR are retained from ARMv8-A, and interact with SVE floating-point
+  operations in a similar way to the way in which they interact with ARMv8
+  floating-point operations.

+(*) callee-save:
+    This only applies to bits [63:0] of Z-/V-registers.
+    FPCR contains callee-save and caller-save bits.  See [4] for details.
+
+
+A.2.  Procedure call standard
+-----------------------------
+
+The ARMv8-A base procedure call standard is extended as follows with respect to
+the additional SVE register state:
+
+* All SVE register bits that are not shared with FP/SIMD are caller-save.
+
+* Z8 bits [63:0] .. Z15 bits [63:0] are callee-save.
+
+  This follows from the way these bits are mapped to V8..V15, which are caller-
+  save in the base procedure call standard.

+===============================================
+
+Note: This section is for information only and not intended to be complete or
+to replace any architectural specification.

+Refer to [4] for for more information.
+

+BPF extensibility and applicability to networking, tracing, security
+in the linux kernel and several user space implementations of BPF
+virtual machine led to a number of misunderstanding on what BPF actually is.
+This short QA is an attempt to address that and outline a direction
+of where BPF is heading long term.
+
+Q: Is BPF a generic instruction set similar to x64 and arm64?
+A: NO.
+
+Q: Is BPF a generic virtual machine ?
+A: NO.
+
+BPF is generic instruction set _with_ C calling convention.
+
+Q: Why C calling convention was chosen?
+A: Because BPF programs are designed to run in the linux kernel
+   which is written in C, hence BPF defines instruction set compatible
+   with two most used architectures x64 and arm64 (and takes into
+   consideration important quirks of other architectures) and
+   defines calling convention that is compatible with C calling
+   convention of the linux kernel on those architectures.
+
+Q: can multiple return values be supported in the future?
+A: NO. BPF allows only register R0 to be used as return value.
+
+Q: can more than 5 function arguments be supported in the future?
+A: NO. BPF calling convention only allows registers R1-R5 to be used
+   as arguments. BPF is not a standalone instruction set.
+   (unlike x64 ISA that allows msft, cdecl and other conventions)
+
+Q: can BPF programs access instruction pointer or return address?
+A: NO.
+
+Q: can BPF programs access stack pointer ?
+A: NO. Only frame pointer (register R10) is accessible.
+   From compiler point of view it's necessary to have stack pointer.
+   For example LLVM defines register R11 as stack pointer in its
+   BPF backend, but it makes sure that generated code never uses it.
+
+Q: Does C-calling convention diminishes possible use cases?
+A: YES. BPF design forces addition of major functionality in the form
+   of kernel helper functions and kernel objects like BPF maps with
+   seamless interoperability between them. It lets kernel call into
+   BPF programs and programs call kernel helpers with zero overhead.
+   As all of them were native C code. That is particularly the case
+   for JITed BPF programs that are indistinguishable from
+   native kernel C code.
+
+Q: Does it mean that 'innovative' extensions to BPF code are disallowed?
+A: Soft yes. At least for now until BPF core has support for
+   bpf-to-bpf calls, indirect calls, loops, global variables,
+   jump tables, read only sections and all other normal constructs
+   that C code can produce.
+
+Q: Can loops be supported in a safe way?
+A: It's not clear yet. BPF developers are trying to find a way to
+   support bounded loops where the verifier can guarantee that
+   the program terminates in less than 4096 instructions.
+
+Q: How come LD_ABS and LD_IND instruction are present in BPF whereas
+   C code cannot express them and has to use builtin intrinsics?
+A: This is artifact of compatibility with classic BPF. Modern
+   networking code in BPF performs better without them.
+   See 'direct packet access'.
+
+Q: It seems not all BPF instructions are one-to-one to native CPU.
+   For example why BPF_JNE and other compare and jumps are not cpu-like?
+A: This was necessary to avoid introducing flags into ISA which are
+   impossible to make generic and efficient across CPU architectures.
+
+Q: why BPF_DIV instruction doesn't map to x64 div?
+A: Because if we picked one-to-one relationship to x64 it would have made
+   it more complicated to support on arm64 and other archs. Also it
+   needs div-by-zero runtime check.
+
+Q: why there is no BPF_SDIV for signed divide operation?
+A: Because it would be rarely used. llvm errors in such case and
+   prints a suggestion to use unsigned divide instead
+
+Q: Why BPF has implicit prologue and epilogue?
+A: Because architectures like sparc have register windows and in general
+   there are enough subtle differences between architectures, so naive
+   store return address into stack won't work. Another reason is BPF has
+   to be safe from division by zero (and legacy exception path
+   of LD_ABS insn). Those instructions need to invoke epilogue and
+   return implicitly.
+
+Q: Why BPF_JLT and BPF_JLE instructions were not introduced in the beginning?
+A: Because classic BPF didn't have them and BPF authors felt that compiler
+   workaround would be acceptable. Turned out that programs lose performance
+   due to lack of these compare instructions and they were added.
+   These two instructions is a perfect example what kind of new BPF
+   instructions are acceptable and can be added in the future.
+   These two already had equivalent instructions in native CPUs.
+   New instructions that don't have one-to-one mapping to HW instructions
+   will not be accepted.
+
+Q: BPF 32-bit subregisters have a requirement to zero upper 32-bits of BPF
+   registers which makes BPF inefficient virtual machine for 32-bit
+   CPU architectures and 32-bit HW accelerators. Can true 32-bit registers
+   be added to BPF in the future?
+A: NO. The first thing to improve performance on 32-bit archs is to teach
+   LLVM to generate code that uses 32-bit subregisters. Then second step
+   is to teach verifier to mark operations where zero-ing upper bits
+   is unnecessary. Then JITs can take advantage of those markings and
+   drastically reduce size of generated code and improve performance.
+
+Q: Does BPF have a stable ABI?
+A: YES. BPF instructions, arguments to BPF programs, set of helper
+   functions and their arguments, recognized return codes are all part
+   of ABI. However when tracing programs are using bpf_probe_read() helper
+   to walk kernel internal datastructures and compile with kernel
+   internal headers these accesses can and will break with newer
+   kernels. The union bpf_attr -> kern_version is checked at load time
+   to prevent accidentally loading kprobe-based bpf programs written
+   for a different kernel. Networking programs don't do kern_version check.
+
+Q: How much stack space a BPF program uses?
+A: Currently all program types are limited to 512 bytes of stack
+   space, but the verifier computes the actual amount of stack used
+   and both interpreter and most JITed code consume necessary amount.
+
+Q: Can BPF be offloaded to HW?
+A: YES. BPF HW offload is supported by NFP driver.
+
+Q: Does classic BPF interpreter still exist?
+A: NO. Classic BPF programs are converted into extend BPF instructions.
+
+Q: Can BPF call arbitrary kernel functions?
+A: NO. BPF programs can only call a set of helper functions which
+   is defined for every program type.
+
+Q: Can BPF overwrite arbitrary kernel memory?
+A: NO. Tracing bpf programs can _read_ arbitrary memory with bpf_probe_read()
+   and bpf_probe_read_str() helpers. Networking programs cannot read
+   arbitrary memory, since they don't have access to these helpers.
+   Programs can never read or write arbitrary memory directly.
+
+Q: Can BPF overwrite arbitrary user memory?
+A: Sort-of. Tracing BPF programs can overwrite the user memory
+   of the current task with bpf_probe_write_user(). Every time such
+   program is loaded the kernel will print warning message, so
+   this helper is only useful for experiments and prototypes.
+   Tracing BPF programs are root only.
+
+Q: When bpf_trace_printk() helper is used the kernel prints nasty
+   warning message. Why is that?
+A: This is done to nudge program authors into better interfaces when
+   programs need to pass data to user space. Like bpf_perf_event_output()
+   can be used to efficiently stream data via perf ring buffer.
+   BPF maps can be used for asynchronous data sharing between kernel
+   and user space. bpf_trace_printk() should only be used for debugging.
+
+Q: Can BPF functionality such as new program or map types, new
+   helpers, etc be added out of kernel module code?
+A: NO.

-Getting started with kmemcheck
-==============================
-
-Vegard Nossum <vegardno@ifi.uio.no>
-
-
-Introduction
-------------
-
-kmemcheck is a debugging feature for the Linux Kernel. More specifically, it
-is a dynamic checker that detects and warns about some uses of uninitialized
-memory.
-
-Userspace programmers might be familiar with Valgrind's memcheck. The main
-difference between memcheck and kmemcheck is that memcheck works for userspace
-programs only, and kmemcheck works for the kernel only. The implementations
-are of course vastly different. Because of this, kmemcheck is not as accurate
-as memcheck, but it turns out to be good enough in practice to discover real
-programmer errors that the compiler is not able to find through static
-analysis.
-
-Enabling kmemcheck on a kernel will probably slow it down to the extent that
-the machine will not be usable for normal workloads such as e.g. an
-interactive desktop. kmemcheck will also cause the kernel to use about twice
-as much memory as normal. For this reason, kmemcheck is strictly a debugging
-feature.
-
-
-Downloading
------------
-
-As of version 2.6.31-rc1, kmemcheck is included in the mainline kernel.
-
-
-Configuring and compiling
--------------------------
-
-kmemcheck only works for the x86 (both 32- and 64-bit) platform. A number of
-configuration variables must have specific settings in order for the kmemcheck
-menu to even appear in "menuconfig". These are:
-
-- ``CONFIG_CC_OPTIMIZE_FOR_SIZE=n``
-	This option is located under "General setup" / "Optimize for size".
-
-	Without this, gcc will use certain optimizations that usually lead to
-	false positive warnings from kmemcheck. An example of this is a 16-bit
-	field in a struct, where gcc may load 32 bits, then discard the upper
-	16 bits. kmemcheck sees only the 32-bit load, and may trigger a
-	warning for the upper 16 bits (if they're uninitialized).
-
-- ``CONFIG_SLAB=y`` or ``CONFIG_SLUB=y``
-	This option is located under "General setup" / "Choose SLAB
-	allocator".
-
-- ``CONFIG_FUNCTION_TRACER=n``
-	This option is located under "Kernel hacking" / "Tracers" / "Kernel
-	Function Tracer"
-
-	When function tracing is compiled in, gcc emits a call to another
-	function at the beginning of every function. This means that when the
-	page fault handler is called, the ftrace framework will be called
-	before kmemcheck has had a chance to handle the fault. If ftrace then
-	modifies memory that was tracked by kmemcheck, the result is an
-	endless recursive page fault.
-
-- ``CONFIG_DEBUG_PAGEALLOC=n``
-	This option is located under "Kernel hacking" / "Memory Debugging"
-	/ "Debug page memory allocations".
-
-In addition, I highly recommend turning on ``CONFIG_DEBUG_INFO=y``. This is also
-located under "Kernel hacking". With this, you will be able to get line number
-information from the kmemcheck warnings, which is extremely valuable in
-debugging a problem. This option is not mandatory, however, because it slows
-down the compilation process and produces a much bigger kernel image.
-
-Now the kmemcheck menu should be visible (under "Kernel hacking" / "Memory
-Debugging" / "kmemcheck: trap use of uninitialized memory"). Here follows
-a description of the kmemcheck configuration variables:
-
-- ``CONFIG_KMEMCHECK``
-	This must be enabled in order to use kmemcheck at all...
-
-- ``CONFIG_KMEMCHECK_``[``DISABLED`` | ``ENABLED`` | ``ONESHOT``]``_BY_DEFAULT``
-	This option controls the status of kmemcheck at boot-time. "Enabled"
-	will enable kmemcheck right from the start, "disabled" will boot the
-	kernel as normal (but with the kmemcheck code compiled in, so it can
-	be enabled at run-time after the kernel has booted), and "one-shot" is
-	a special mode which will turn kmemcheck off automatically after
-	detecting the first use of uninitialized memory.
-
-	If you are using kmemcheck to actively debug a problem, then you
-	probably want to choose "enabled" here.
-
-	The one-shot mode is mostly useful in automated test setups because it
-	can prevent floods of warnings and increase the chances of the machine
-	surviving in case something is really wrong. In other cases, the one-
-	shot mode could actually be counter-productive because it would turn
-	itself off at the very first error -- in the case of a false positive
-	too -- and this would come in the way of debugging the specific
-	problem you were interested in.
-
-	If you would like to use your kernel as normal, but with a chance to
-	enable kmemcheck in case of some problem, it might be a good idea to
-	choose "disabled" here. When kmemcheck is disabled, most of the run-
-	time overhead is not incurred, and the kernel will be almost as fast
-	as normal.
-
-- ``CONFIG_KMEMCHECK_QUEUE_SIZE``
-	Select the maximum number of error reports to store in an internal
-	(fixed-size) buffer. Since errors can occur virtually anywhere and in
-	any context, we need a temporary storage area which is guaranteed not
-	to generate any other page faults when accessed. The queue will be
-	emptied as soon as a tasklet may be scheduled. If the queue is full,
-	new error reports will be lost.
-
-	The default value of 64 is probably fine. If some code produces more
-	than 64 errors within an irqs-off section, then the code is likely to
-	produce many, many more, too, and these additional reports seldom give
-	any more information (the first report is usually the most valuable
-	anyway).
-
-	This number might have to be adjusted if you are not using serial
-	console or similar to capture the kernel log. If you are using the
-	"dmesg" command to save the log, then getting a lot of kmemcheck
-	warnings might overflow the kernel log itself, and the earlier reports
-	will get lost in that way instead. Try setting this to 10 or so on
-	such a setup.
-
-- ``CONFIG_KMEMCHECK_SHADOW_COPY_SHIFT``
-	Select the number of shadow bytes to save along with each entry of the
-	error-report queue. These bytes indicate what parts of an allocation
-	are initialized, uninitialized, etc. and will be displayed when an
-	error is detected to help the debugging of a particular problem.
-
-	The number entered here is actually the logarithm of the number of
-	bytes that will be saved. So if you pick for example 5 here, kmemcheck
-	will save 2^5 = 32 bytes.
-
-	The default value should be fine for debugging most problems. It also
-	fits nicely within 80 columns.
-
-- ``CONFIG_KMEMCHECK_PARTIAL_OK``
-	This option (when enabled) works around certain GCC optimizations that
-	produce 32-bit reads from 16-bit variables where the upper 16 bits are
-	thrown away afterwards.
-
-	The default value (enabled) is recommended. This may of course hide
-	some real errors, but disabling it would probably produce a lot of
-	false positives.
-
-- ``CONFIG_KMEMCHECK_BITOPS_OK``
-	This option silences warnings that would be generated for bit-field
-	accesses where not all the bits are initialized at the same time. This
-	may also hide some real bugs.
-
-	This option is probably obsolete, or it should be replaced with
-	the kmemcheck-/bitfield-annotations for the code in question. The
-	default value is therefore fine.
-
-Now compile the kernel as usual.
-
-
-How to use
-----------
-
-Booting
-~~~~~~~
-
-First some information about the command-line options. There is only one
-option specific to kmemcheck, and this is called "kmemcheck". It can be used
-to override the default mode as chosen by the ``CONFIG_KMEMCHECK_*_BY_DEFAULT``
-option. Its possible settings are:
-
-- ``kmemcheck=0`` (disabled)
-- ``kmemcheck=1`` (enabled)
-- ``kmemcheck=2`` (one-shot mode)
-
-If SLUB debugging has been enabled in the kernel, it may take precedence over
-kmemcheck in such a way that the slab caches which are under SLUB debugging
-will not be tracked by kmemcheck. In order to ensure that this doesn't happen
-(even though it shouldn't by default), use SLUB's boot option ``slub_debug``,
-like this: ``slub_debug=-``
-
-In fact, this option may also be used for fine-grained control over SLUB vs.
-kmemcheck. For example, if the command line includes
-``kmemcheck=1 slub_debug=,dentry``, then SLUB debugging will be used only
-for the "dentry" slab cache, and with kmemcheck tracking all the other
-caches. This is advanced usage, however, and is not generally recommended.
-
-
-Run-time enable/disable
-~~~~~~~~~~~~~~~~~~~~~~~
-
-When the kernel has booted, it is possible to enable or disable kmemcheck at
-run-time. WARNING: This feature is still experimental and may cause false
-positive warnings to appear. Therefore, try not to use this. If you find that
-it doesn't work properly (e.g. you see an unreasonable amount of warnings), I
-will be happy to take bug reports.
-
-Use the file ``/proc/sys/kernel/kmemcheck`` for this purpose, e.g.::
-
-	$ echo 0 > /proc/sys/kernel/kmemcheck # disables kmemcheck
-
-The numbers are the same as for the ``kmemcheck=`` command-line option.
-
-
-Debugging

-
-The single most valuable information in this report is the RIP (or EIP on 32-
-bit) value. This will help us pinpoint exactly which instruction that caused
-the warning.
-
-If your kernel was compiled with ``CONFIG_DEBUG_INFO=y``, then all we have to do
-is give this address to the addr2line program, like this::
-
-	$ addr2line -e vmlinux -i ffffffff8104ede8
-	arch/x86/include/asm/string_64.h:12
-	include/asm-generic/siginfo.h:287
-	kernel/signal.c:380
-	kernel/signal.c:410
-
-The "``-e vmlinux``" tells addr2line which file to look in. **IMPORTANT:**
-This must be the vmlinux of the kernel that produced the warning in the
-first place! If not, the line number information will almost certainly be
-wrong.
-
-The "``-i``" tells addr2line to also print the line numbers of inlined
-functions.  In this case, the flag was very important, because otherwise,
-it would only have printed the first line, which is just a call to
-``memcpy()``, which could be called from a thousand places in the kernel, and
-is therefore not very useful.  These inlined functions would not show up in
-the stack trace above, simply because the kernel doesn't load the extra
-debugging information. This technique can of course be used with ordinary
-kernel oopses as well.
-
-In this case, it's the caller of ``memcpy()`` that is interesting, and it can be
-found in ``include/asm-generic/siginfo.h``, line 287::
-
-    281 static inline void copy_siginfo(struct siginfo *to, struct siginfo *from)
-    282 {
-    283         if (from->si_code < 0)
-    284                 memcpy(to, from, sizeof(*to));
-    285         else
-    286                 /* _sigchld is currently the largest know union member */
-    287                 memcpy(to, from, __ARCH_SI_PREAMBLE_SIZE + sizeof(from->_sifields._sigchld));
-    288 }
-
-Since this was a read (kmemcheck usually warns about reads only, though it can
-warn about writes to unallocated or freed memory as well), it was probably the
-"from" argument which contained some uninitialized bytes. Following the chain
-of calls, we move upwards to see where "from" was allocated or initialized,
-``kernel/signal.c``, line 380::
-
-    359 static void collect_signal(int sig, struct sigpending *list, siginfo_t *info)
-    360 {
-    ...
-    367         list_for_each_entry(q, &list->list, list) {
-    368                 if (q->info.si_signo == sig) {
-    369                         if (first)
-    370                                 goto still_pending;
-    371                         first = q;
-    ...
-    377         if (first) {
-    378 still_pending:
-    379                 list_del_init(&first->list);
-    380                 copy_siginfo(info, &first->info);
-    381                 __sigqueue_free(first);
-    ...
-    392         }
-    393 }
-
-Here, it is ``&first->info`` that is being passed on to ``copy_siginfo()``. The
-variable ``first`` was found on a list -- passed in as the second argument to
-``collect_signal()``. We  continue our journey through the stack, to figure out
-where the item on "list" was allocated or initialized. We move to line 410::
-
-    395 static int __dequeue_signal(struct sigpending *pending, sigset_t *mask,
-    396                         siginfo_t *info)
-    397 {
-    ...
-    410                 collect_signal(sig, pending, info);
-    ...
-    414 }
-
-Now we need to follow the ``pending`` pointer, since that is being passed on to
-``collect_signal()`` as ``list``. At this point, we've run out of lines from the
-"addr2line" output. Not to worry, we just paste the next addresses from the
-kmemcheck stack dump, i.e.::
-
-     [<ffffffff8104f04e>] dequeue_signal+0x8e/0x170
-     [<ffffffff81050bd8>] get_signal_to_deliver+0x98/0x390
-     [<ffffffff8100b87d>] do_notify_resume+0xad/0x7d0
-     [<ffffffff8100c7b5>] int_signal+0x12/0x17
-
-	$ addr2line -e vmlinux -i ffffffff8104f04e ffffffff81050bd8 \
-		ffffffff8100b87d ffffffff8100c7b5
-	kernel/signal.c:446
-	kernel/signal.c:1806
-	arch/x86/kernel/signal.c:805
-	arch/x86/kernel/signal.c:871
-	arch/x86/kernel/entry_64.S:694
-
-Remember that since these addresses were found on the stack and not as the
-RIP value, they actually point to the _next_ instruction (they are return
-addresses). This becomes obvious when we look at the code for line 446::
-
-    422 int dequeue_signal(struct task_struct *tsk, sigset_t *mask, siginfo_t *info)
-    423 {
-    ...
-    431                 signr = __dequeue_signal(&tsk->signal->shared_pending,
-    432						 mask, info);
-    433			/*
-    434			 * itimer signal ?
-    435			 *
-    436			 * itimers are process shared and we restart periodic
-    437			 * itimers in the signal delivery path to prevent DoS
-    438			 * attacks in the high resolution timer case. This is
-    439			 * compliant with the old way of self restarting
-    440			 * itimers, as the SIGALRM is a legacy signal and only
-    441			 * queued once. Changing the restart behaviour to
-    442			 * restart the timer in the signal dequeue path is
-    443			 * reducing the timer noise on heavy loaded !highres
-    444			 * systems too.
-    445			 */
-    446			if (unlikely(signr == SIGALRM)) {
-    ...
-    489 }
-
-So instead of looking at 446, we should be looking at 431, which is the line
-that executes just before 446. Here we see that what we are looking for is
-``&tsk->signal->shared_pending``.
-
-Our next task is now to figure out which function that puts items on this
-``shared_pending`` list. A crude, but efficient tool, is ``git grep``::
-
-	$ git grep -n 'shared_pending' kernel/
-	...
-	kernel/signal.c:828:	pending = group ? &t->signal->shared_pending : &t->pending;
-	kernel/signal.c:1339:	pending = group ? &t->signal->shared_pending : &t->pending;
-	...
-
-There were more results, but none of them were related to list operations,
-and these were the only assignments. We inspect the line numbers more closely
-and find that this is indeed where items are being added to the list::
-
-    816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t,
-    817				int group)
-    818 {
-    ...
-    828		pending = group ? &t->signal->shared_pending : &t->pending;
-    ...
-    851		q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN &&
-    852						     (is_si_special(info) ||
-    853						      info->si_code >= 0)));
-    854		if (q) {
-    855			list_add_tail(&q->list, &pending->list);
-    ...
-    890 }
-
-and::
-
-    1309 int send_sigqueue(struct sigqueue *q, struct task_struct *t, int group)
-    1310 {
-    ....
-    1339	 pending = group ? &t->signal->shared_pending : &t->pending;
-    1340	 list_add_tail(&q->list, &pending->list);
-    ....
-    1347 }
-
-In the first case, the list element we are looking for, ``q``, is being
-returned from the function ``__sigqueue_alloc()``, which looks like an
-allocation function.  Let's take a look at it::
-
-    187 static struct sigqueue *__sigqueue_alloc(struct task_struct *t, gfp_t flags,
-    188						 int override_rlimit)
-    189 {
-    190		struct sigqueue *q = NULL;
-    191		struct user_struct *user;
-    192
-    193		/*
-    194		 * We won't get problems with the target's UID changing under us
-    195		 * because changing it requires RCU be used, and if t != current, the
-    196		 * caller must be holding the RCU readlock (by way of a spinlock) and
-    197		 * we use RCU protection here
-    198		 */
-    199		user = get_uid(__task_cred(t)->user);
-    200		atomic_inc(&user->sigpending);
-    201		if (override_rlimit ||
-    202		    atomic_read(&user->sigpending) <=
-    203				t->signal->rlim[RLIMIT_SIGPENDING].rlim_cur)
-    204			q = kmem_cache_alloc(sigqueue_cachep, flags);
-    205		if (unlikely(q == NULL)) {
-    206			atomic_dec(&user->sigpending);
-    207			free_uid(user);
-    208		} else {
-    209			INIT_LIST_HEAD(&q->list);
-    210			q->flags = 0;
-    211			q->user = user;
-    212		}
-    213
-    214		return q;
-    215 }
-
-We see that this function initializes ``q->list``, ``q->flags``, and
-``q->user``. It seems that now is the time to look at the definition of
-``struct sigqueue``, e.g.::

-
-And, you might remember, it was a ``memcpy()`` on ``&first->info`` that
-caused the warning, so this makes perfect sense. It also seems reasonable
-to assume that it is the caller of ``__sigqueue_alloc()`` that has the
-responsibility of filling out (initializing) this member.
-
-But just which fields of the struct were uninitialized? Let's look at
-kmemcheck's report again::
-
-    WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024)
-    80000000000000000000000000000000000000000088ffff0000000000000000
-     i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u
-	     ^
-
-These first two lines are the memory dump of the memory object itself, and
-the shadow bytemap, respectively. The memory object itself is in this case
-``&first->info``. Just beware that the start of this dump is NOT the start
-of the object itself! The position of the caret (^) corresponds with the
-address of the read (ffff88003e4a2024).
-
-The shadow bytemap dump legend is as follows:
-
-- i: initialized
-- u: uninitialized
-- a: unallocated (memory has been allocated by the slab layer, but has not
-  yet been handed off to anybody)
-- f: freed (memory has been allocated by the slab layer, but has been freed
-  by the previous owner)
-
-In order to figure out where (relative to the start of the object) the
-uninitialized memory was located, we have to look at the disassembly. For
-that, we'll need the RIP address again::
-
-    RIP: 0010:[<ffffffff8104ede8>]  [<ffffffff8104ede8>] __dequeue_signal+0xc8/0x190
-
-	$ objdump -d --no-show-raw-insn vmlinux | grep -C 8 ffffffff8104ede8:

-	ffffffff8104edf4:	movsb  %ds:(%rsi),%es:(%rdi)
-	ffffffff8104edf5:	mov    %r8,%rdi
-	ffffffff8104edf8:	callq  ffffffff8104de60 <__sigqueue_free>
-
-As expected, it's the "``rep movsl``" instruction from the ``memcpy()``
-that causes the warning. We know about ``REP MOVSL`` that it uses the register
-``RCX`` to count the number of remaining iterations. By taking a look at the
-register dump again (from the kmemcheck report), we can figure out how many
-bytes were left to copy::
-
-    RAX: 0000000000000030 RBX: ffff88003d4ea968 RCX: 0000000000000009
-
-By looking at the disassembly, we also see that ``%ecx`` is being loaded
-with the value ``$0xc`` just before (ffffffff8104edd8), so we are very
-lucky. Keep in mind that this is the number of iterations, not bytes. And
-since this is a "long" operation, we need to multiply by 4 to get the
-number of bytes. So this means that the uninitialized value was encountered
-at 4 * (0xc - 0x9) = 12 bytes from the start of the object.
-
-We can now try to figure out which field of the "``struct siginfo``" that
-was not initialized. This is the beginning of the struct::
-
-    40 typedef struct siginfo {
-    41	       int si_signo;
-    42	       int si_errno;
-    43	       int si_code;
-    44
-    45	       union {
-    ..
-    92	       } _sifields;
-    93 } siginfo_t;
-
-On 64-bit, the int is 4 bytes long, so it must the union member that has
-not been initialized. We can verify this using gdb::
-
-	$ gdb vmlinux
-	...
-	(gdb) p &((struct siginfo *) 0)->_sifields
-	$1 = (union {...} *) 0x10
-
-Actually, it seems that the union member is located at offset 0x10 -- which
-means that gcc has inserted 4 bytes of padding between the members ``si_code``
-and ``_sifields``. We can now get a fuller picture of the memory dump::
-
-		 _----------------------------=> si_code
-		/	 _--------------------=> (padding)
-	       |	/	 _------------=> _sifields(._kill._pid)
-	       |       |	/	 _----=> _sifields(._kill._uid)
-	       |       |       |	/
-	-------|-------|-------|-------|
-	80000000000000000000000000000000000000000088ffff0000000000000000
-	 i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u
-
-This allows us to realize another important fact: ``si_code`` contains the
-value 0x80. Remember that x86 is little endian, so the first 4 bytes
-"80000000" are really the number 0x00000080. With a bit of research, we
-find that this is actually the constant ``SI_KERNEL`` defined in
-``include/asm-generic/siginfo.h``::
-
-    144 #define SI_KERNEL	0x80		/* sent by the kernel from somewhere	 */
-
-This macro is used in exactly one place in the x86 kernel: In ``send_signal()``
-in ``kernel/signal.c``::
-
-    816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t,
-    817				int group)
-    818 {
-    ...
-    828		pending = group ? &t->signal->shared_pending : &t->pending;
-    ...
-    851		q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN &&
-    852						     (is_si_special(info) ||
-    853						      info->si_code >= 0)));
-    854		if (q) {
-    855			list_add_tail(&q->list, &pending->list);
-    856			switch ((unsigned long) info) {
-    ...
-    865			case (unsigned long) SEND_SIG_PRIV:
-    866				q->info.si_signo = sig;
-    867				q->info.si_errno = 0;
-    868				q->info.si_code = SI_KERNEL;
-    869				q->info.si_pid = 0;
-    870				q->info.si_uid = 0;
-    871				break;
-    ...
-    890 }
-
-Not only does this match with the ``.si_code`` member, it also matches the place
-we found earlier when looking for where siginfo_t objects are enqueued on the
-``shared_pending`` list.
-
-So to sum up: It seems that it is the padding introduced by the compiler
-between two struct fields that is uninitialized, and this gets reported when
-we do a ``memcpy()`` on the struct. This means that we have identified a false
-positive warning.
-
-Normally, kmemcheck will not report uninitialized accesses in ``memcpy()`` calls
-when both the source and destination addresses are tracked. (Instead, we copy
-the shadow bytemap as well). In this case, the destination address clearly
-was not tracked. We can dig a little deeper into the stack trace from above::
-
-	arch/x86/kernel/signal.c:805
-	arch/x86/kernel/signal.c:871
-	arch/x86/kernel/entry_64.S:694
-
-And we clearly see that the destination siginfo object is located on the
-stack::
-
-    782 static void do_signal(struct pt_regs *regs)
-    783 {
-    784		struct k_sigaction ka;
-    785		siginfo_t info;
-    ...
-    804		signr = get_signal_to_deliver(&info, &ka, regs, NULL);
-    ...
-    854 }
-
-And this ``&info`` is what eventually gets passed to ``copy_siginfo()`` as the
-destination argument.
-
-Now, even though we didn't find an actual error here, the example is still a
-good one, because it shows how one would go about to find out what the report
-was all about.
-
-
-Annotating false positives
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-There are a few different ways to make annotations in the source code that
-will keep kmemcheck from checking and reporting certain allocations. Here
-they are:
-
-- ``__GFP_NOTRACK_FALSE_POSITIVE``
-	This flag can be passed to ``kmalloc()`` or ``kmem_cache_alloc()``
-	(therefore also to other functions that end up calling one of
-	these) to indicate that the allocation should not be tracked
-	because it would lead to a false positive report. This is a "big
-	hammer" way of silencing kmemcheck; after all, even if the false
-	positive pertains to particular field in a struct, for example, we
-	will now lose the ability to find (real) errors in other parts of
-	the same struct.
-
-	Example::
-
-	    /* No warnings will ever trigger on accessing any part of x */
-	    x = kmalloc(sizeof *x, GFP_KERNEL | __GFP_NOTRACK_FALSE_POSITIVE);
-
-- ``kmemcheck_bitfield_begin(name)``/``kmemcheck_bitfield_end(name)`` and
-	``kmemcheck_annotate_bitfield(ptr, name)``
-	The first two of these three macros can be used inside struct
-	definitions to signal, respectively, the beginning and end of a
-	bitfield. Additionally, this will assign the bitfield a name, which
-	is given as an argument to the macros.
-
-	Having used these markers, one can later use
-	kmemcheck_annotate_bitfield() at the point of allocation, to indicate
-	which parts of the allocation is part of a bitfield.
-
-	Example::
-
-	    struct foo {
-		int x;
-
-		kmemcheck_bitfield_begin(flags);
-		int flag_a:1;
-		int flag_b:1;
-		kmemcheck_bitfield_end(flags);
-
-		int y;
-	    };
-
-	    struct foo *x = kmalloc(sizeof *x);
-
-	    /* No warnings will trigger on accessing the bitfield of x */
-	    kmemcheck_annotate_bitfield(x, flags);
-
-	Note that ``kmemcheck_annotate_bitfield()`` can be used even before the
-	return value of ``kmalloc()`` is checked -- in other words, passing NULL
-	as the first argument is legal (and will do nothing).
-
-
-Reporting errors
-----------------
-
-As we have seen, kmemcheck will produce false positive reports. Therefore, it
-is not very wise to blindly post kmemcheck warnings to mailing lists and
-maintainers. Instead, I encourage maintainers and developers to find errors
-in their own code. If you get a warning, you can try to work around it, try
-to figure out if it's a real error or not, or simply ignore it. Most
-developers know their own code and will quickly and efficiently determine the
-root cause of a kmemcheck report. This is therefore also the most efficient
-way to work with kmemcheck.
-
-That said, we (the kmemcheck maintainers) will always be on the lookout for
-false positives that we can annotate and silence. So whatever you find,
-please drop us a note privately! Kernel configs and steps to reproduce (if
-available) are of course a great help too.
-
-Happy hacking!
-
-
-Technical description
----------------------
-
-kmemcheck works by marking memory pages non-present. This means that whenever
-somebody attempts to access the page, a page fault is generated. The page
-fault handler notices that the page was in fact only hidden, and so it calls
-on the kmemcheck code to make further investigations.
-
-When the investigations are completed, kmemcheck "shows" the page by marking
-it present (as it would be under normal circumstances). This way, the
-interrupted code can continue as usual.
-
-But after the instruction has been executed, we should hide the page again, so
-that we can catch the next access too! Now kmemcheck makes use of a debugging
-feature of the processor, namely single-stepping. When the processor has
-finished the one instruction that generated the memory access, a debug
-exception is raised. From here, we simply hide the page again and continue
-execution, this time with the single-stepping feature turned off.
-
-kmemcheck requires some assistance from the memory allocator in order to work.
-The memory allocator needs to
-
-  1. Tell kmemcheck about newly allocated pages and pages that are about to
-     be freed. This allows kmemcheck to set up and tear down the shadow memory
-     for the pages in question. The shadow memory stores the status of each
-     byte in the allocation proper, e.g. whether it is initialized or
-     uninitialized.
-
-  2. Tell kmemcheck which parts of memory should be marked uninitialized.
-     There are actually a few more states, such as "not yet allocated" and
-     "recently freed".
-
-If a slab cache is set up using the SLAB_NOTRACK flag, it will never return
-memory that can take page faults because of kmemcheck.
-
-If a slab cache is NOT set up using the SLAB_NOTRACK flag, callers can still
-request memory with the __GFP_NOTRACK or __GFP_NOTRACK_FALSE_POSITIVE flags.
-This does not prevent the page faults from occurring, however, but marks the
-object in question as being initialized so that no warnings will ever be
-produced for this object.
-
-Currently, the SLAB and SLUB allocators are supported by kmemcheck.
