-/*
|
|
|
- * The set_memory_* API can be used to change various attributes of a virtual
|
|
|
- * address range. The attributes include:
|
|
|
- * Cachability : UnCached, WriteCombining, WriteThrough, WriteBack
|
|
|
- * Executability : eXeutable, NoteXecutable
|
|
|
- * Read/Write : ReadOnly, ReadWrite
|
|
|
- * Presence : NotPresent
|
|
|
- *
|
|
|
- * Within a category, the attributes are mutually exclusive.
|
|
|
- *
|
|
|
- * The implementation of this API will take care of various aspects that
|
|
|
- * are associated with changing such attributes, such as:
|
|
|
- * - Flushing TLBs
|
|
|
- * - Flushing CPU caches
|
|
|
- * - Making sure aliases of the memory behind the mapping don't violate
|
|
|
- * coherency rules as defined by the CPU in the system.
|
|
|
- *
|
|
|
- * What this API does not do:
|
|
|
- * - Provide exclusion between various callers - including callers that
|
|
|
- * operation on other mappings of the same physical page
|
|
|
- * - Restore default attributes when a page is freed
|
|
|
- * - Guarantee that mappings other than the requested one are
|
|
|
- * in any state, other than that these do not violate rules for
|
|
|
- * the CPU you have. Do not depend on any effects on other mappings,
|
|
|
- * CPUs other than the one you have may have more relaxed rules.
|
|
|
- * The caller is required to take care of these.

|
- * For legacy compatibility with the old APIs, a few functions
|
|
|
- * are provided that work on a "struct page".
|
|
|
- * These functions operate ONLY on the 1:1 kernel mapping of the
|
|
|
- * memory that the struct page represents, and internally just
|
|
|
- * call the set_memory_* function. See the description of the
|
|
|
- * set_memory_* function for more details on conventions.
|
|
|
- *
|
|
|
- * These APIs should be considered *deprecated* and are likely going to
|
|
|
- * be removed in the future.
|
|
|
- * The reason for this is the implicit operation on the 1:1 mapping only,
|
|
|
- * making this not a generally useful API.
|
|
|
- *
|
|
|
- * Specifically, many users of the old APIs had a virtual address,
|
|
|
- * called virt_to_page() or vmalloc_to_page() on that address to
|
|
|
- * get a struct page* that the old API required.
|
|
|
- * To convert these cases, use set_memory_*() on the original
|
|
|
- * virtual address, do not use these functions.
