+Add musl support to gcc
+
+This patch comes from the musl-cross project at
+https://bitbucket.org/GregorR/musl-cross/src. Compared to the upstream version:
+
+ * the config.sub modifications have been removed, because Buildroot
+   already overwrites all config.sub with a more recent config.sub
+   that has musl support.
+
+ * change to ensure that a dummy dynamic linker path
+   MUSL_DYNAMIC_LINKER<foo> is defined for all architectures,
+   otherwise building gcc for architectures not supported by musl was
+   causing build failure. Bug reported upstream at
+   https://bitbucket.org/GregorR/musl-gcc-patches/issue/4/musl-gcc-patches-break-the-build-on.
+
+[Gustavo: remove upstream applied gcc/config/sh/sh.c chunk for 4.9.1]

+Allow C99-depending features of libstdc++ with uClibc
+
+The libstdc++ code is fairly restrictive on how it checks for C99
+compatibility: it requires *complete* C99 support to enable certain
+features. For example, uClibc provides a good number of C99 features,
+but not C99 complex number support. For this reason, libstdc++
+completely disables many the standard C++ methods that can in fact
+work because uClibc provides the necessary functions.
+
+This patch is similar and highly inspired from
+https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
+a way that doesn't involve changing the configure.ac script, as
+autoreconfiguring gcc is complicated. It simply relies on the fact
+that uClibc defines the __UCLIBC__ definition.

+Subject: [PATCH] xtensa: add -mauto-litpools option
+
+With support from assembler this option allows compiling huge functions,
+where single literal pool at the beginning of a function may not be
+reachable by L32R instructions at its end.
+
+Currently assembler --auto-litpools option cannot deal with literals
+used from multiple locations separated by more than 256 KBytes of code.
+Don't turn constants into literals, instead use MOVI instruction to load
+them into registers and let the assembler turn them into literals as
+necessary.
+
+2015-08-12  Max Filippov  <jcmvbkbc@gmail.com>
+gcc/
+	* config/xtensa/constraints.md (define_constraint "Y"): New
+	constraint.
+	* config/xtensa/elf.h (ASM_SPEC): Add m(no-)auto-litpools.
+	* config/xtensa/linux.h (ASM_SPEC): Likewise.
+	* config/xtensa/predicates.md (move_operand): Match constants
+	and symbols in the presence of TARGET_AUTO_LITPOOLS.
+	* config/xtensa/xtensa.c (xtensa_valid_move): Don't allow
+	immediate references to TLS data.
+	(xtensa_emit_move_sequence): Don't force constants to memory in
+	the presence of TARGET_AUTO_LITPOOLS.
+	(print_operand): Add 'y' format, same as default, but capable of
+	printing SF mode constants as well.
+	* config/xtensa/xtensa.md (movsi_internal, movhi_internal)
+	(movsf_internal): Add movi pattern that loads literal.
+	(movsf, movdf): Don't force constants to memory in the presence
+	of TARGET_AUTO_LITPOOLS.
+	(movdf_internal): Add 'Y' constraint.
+	* config/xtensa/xtensa.opt (mauto-litpools): New option.

+Subject: [PATCH 1/3] xtensa: reimplement register spilling
+
+Spilling windowed registers in userspace is much easier, more portable,
+less error-prone and equally effective as in kernel. Now that register
+spilling syscall is considered obsolete in the xtensa linux kernel
+replace it with CALL12 followed by series of ENTRY in libgcc.
+
+2015-08-18  Max Filippov  <jcmvbkbc@gmail.com>
+libgcc/
+	* config/xtensa/lib2funcs.S (__xtensa_libgcc_window_spill): Use
+	CALL12 followed by series of ENTRY to spill windowed registers.
+	(__xtensa_nonlocal_goto): Call __xtensa_libgcc_window_spill
+	instead of making linux spill syscall.

+Returning context->cfa in _Unwind_GetCFA makes CFA point one stack frame
+higher than what was actually used by code at context->ra. This results
+in invalid CFA value in signal frames and premature unwinding completion
+in forced unwinding used by uClibc NPTL thread cancellation.

+Add musl support to gcc
+
+This patch comes from the musl-cross project at
+https://bitbucket.org/GregorR/musl-cross/src. Compared to the upstream version:
+
+ * the config.sub modifications have been removed, because Buildroot
+   already overwrites all config.sub with a more recent config.sub
+   that has musl support.
+
+ * change to ensure that a dummy dynamic linker path
+   MUSL_DYNAMIC_LINKER<foo> is defined for all architectures,
+   otherwise building gcc for architectures not supported by musl was
+   causing build failure. Bug reported upstream at
+   https://bitbucket.org/GregorR/musl-gcc-patches/issue/4/musl-gcc-patches-break-the-build-on.
+
+ * change the USE_PT_GNU_EH_FRAME logic to keep the existing gcc logic
+   and only add the musl one as an addition, not as a replacement. Not
+   doing this breaks C++ exception handling with glibc, because
+   USE_PT_GNU_EH_FRAME doesn't get defined due to the configure script
+   not testing dl_iterate_phdr() on any system except Solaris.
+
+[Gustavo: remove upstream applied gcc/config/sh/sh.c chunk for 4.9.1]

+
+CVE-2014-7817:
+
+The function wordexp() fails to properly handle the WRDE_NOCMD
+flag when processing arithmetic inputs in the form of "$((... ``))"
+where "..." can be anything valid. The backticks in the arithmetic
+epxression are evaluated by in a shell even if WRDE_NOCMD forbade
+command substitution. This allows an attacker to attempt to pass
+dangerous commands via constructs of the above form, and bypass
+the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
+in parse_arith(). The patch also hardens parse_backticks() and 
+parse_comm() to check for WRDE_NOCMD flag and return an error instead
+of ever running a shell.
+
+We expand the testsuite and add 3 new regression tests of roughtly
+the same form but with a couple of nested levels. 
+
+On top of the 3 new tests we add fork validation to the WRDE_NOCMD
+testing. If any forks are detected during the execution of a wordexp()
+call with WRDE_NOCMD, the test is marked as failed. This is slightly
+heuristic since vfork might be used, but it provides a higher level
+of assurance that no shells were executed as part of command substitution
+with WRDE_NOCMD in effect. In addition it doesn't require libpthread or
+libdl, instead we use the public implementation namespace function
+__register_atfork (already part of the public ABI for libpthread).
+
+Tested on x86_64 with no regressions.

+
+CVE-2014-7817:
+
+The function wordexp() fails to properly handle the WRDE_NOCMD
+flag when processing arithmetic inputs in the form of "$((... ``))"
+where "..." can be anything valid. The backticks in the arithmetic
+epxression are evaluated by in a shell even if WRDE_NOCMD forbade
+command substitution. This allows an attacker to attempt to pass
+dangerous commands via constructs of the above form, and bypass
+the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
+in parse_arith(). The patch also hardens parse_backticks() and 
+parse_comm() to check for WRDE_NOCMD flag and return an error instead
+of ever running a shell.
+
+We expand the testsuite and add 3 new regression tests of roughtly
+the same form but with a couple of nested levels. 
+
+On top of the 3 new tests we add fork validation to the WRDE_NOCMD
+testing. If any forks are detected during the execution of a wordexp()
+call with WRDE_NOCMD, the test is marked as failed. This is slightly
+heuristic since vfork might be used, but it provides a higher level
+of assurance that no shells were executed as part of command substitution
+with WRDE_NOCMD in effect. In addition it doesn't require libpthread or
+libdl, instead we use the public implementation namespace function
+__register_atfork (already part of the public ABI for libpthread).
+
+Tested on x86_64 with no regressions.
+
+2014-10-27  Carlos O'Donell  <carlos@redhat.com>
+
+	* wordexp-test.c (__dso_handle): Add prototype.
+	(__register_atfork): Likewise.
+	(__app_register_atfork): New function.
+	(registered_forks): New global.
+	(register_fork): New function.
+	(test_case): Add 3 new tests for WRDE_CMDSUB.
+	(main): Call __app_register_atfork.
+	(testit): If WRDE_NOCMD set registered_forks to zero, run test, and
+	if fork count is non-zero fail the test.
+	* posix/wordexp.c (parse_arith): Return WRDE_NOCMD if WRDE_NOCMD flag
+	is set and parsing '`'. 
+	(parse_comm): Return WRDE_NOCMD if WRDE_NOCMD flag is set.
+	(parse_backtick): Return WRDE_NOCMD if WRDE_NOCMD flag is set and
+	parsing '`'.

+From: Mike Frysinger <vapier@gentoo.org>
+Date: Thu, 6 Aug 2015 02:10:46 -0400
+Subject: [PATCH] microblaze: include unix/sysdep.h
+
+The semi-recent SYSCALL_CANCEL inclusion broke microblaze due to the
+sysdep.h header not including the unix/sysdep.h header.  Include it
+here like all other ports.
+
+(cherry picked from commit 5d5de49c3ccd69f65b801f1ca490a0112d1cbd7d)

+Date: Thu, 3 Mar 2016 15:17:31 +0100
+Subject: [PATCH] Disable c++ standard compiler flags for the host build
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There is no test for c++ standard support for the host build
+(only for the target compiler/build) which leads to trouble
+in some cross compiling environments (old host compiler, new
+cross compiler):
+
+  g++: error: unrecognized command line option ‘-std=c++1z’
+
+So disable c++ standard compiler flags unconditionally for host builds.
+
+Task-number: QTBUG-51644
+Change-Id: Ifb3042e125fe199a7e081740d1171d26ccacf0c5

+From: Allan Sandfeld Jensen <allan.jensen@theqtcompany.com>
+Date: Mon, 22 Feb 2016 10:57:32 +0100
+Subject: [PATCH] Fix linking with libpthread
+
+WebKit use libpthread directly but is depending on other qt modules
+causing it to be linked against, which might break unless -lpthread
+is last. Instead just add it explicitly after the static libraries.
+
+Upstream-Status: Backport from 5.7 branch
+
