637461d965 Clean up kernel version conditionals for pre-2.6.32 kernels.
This patch does some initial cleanup, following the move to 2.6.32
minimum kernel version, by removing __LINUX_KERNEL_VERSION
conditionals that are now always-true or always-false.  In the case of
__ASSUME_ARG_MAX_STACK_BASED, where the conditional used a kernel
version that was itself in a macro, the associated sysconf.c code is
also cleaned up and __ASSUME_ARG_MAX_STACK_BASED removed completely.

Tested x86_64 that disassembly of installed shared libraries is
unchanged by the patch.

77d08acaad Include SSE state in i386 fenv_t (bug 16064).
This patch fixes bug 16064, i386 fenv_t not including SSE state, using
the technique suggested there of storing the state in the existing
__eip field of fenv_t to avoid needing to increase the size of fenv_t
and add new symbol versions.  The included testcase, which previously
failed for i386 (but passed for x86_64), illustrates how the previous
state was buggy.

This patch causes the SSE state to be included *to the extent it is on
x86_64*.  Where some state should logically be included but isn't for
x86_64 (see bug 16068), this patch does not cause it to be included
for i386 either.  The idea is that any patch fixing that bug should
fix it for both x86_64 and i386 at once.

Tested i386 and x86_64.  (I haven't tested the case of a CPU without
SSE2 disabling the test.)

	* sysdeps/i386/fpu/fegetenv.c: Include <unistd.h>, <ldsodefs.h>
	and <dl-procinfo.h>.

	__data_offset and __data_selector in environment to 0.  Set SSE

5a414ff70c S/390: Port of lock elision to System/z
Added support for TX lock elision of pthread mutexes on s390 and
s390x.  This may improve lock scaling of existing programs on TX
capable systems.  The lock elision code is only built with
--enable-lock-elision=yes and then requires a GCC version supporting
the TX builtins.  With lock elision default mutexes are elided via
__builtin_tbegin, if the cpu supports transactions. By default lock
elision is not enabled and the elision code is not built.

f63c86fed0 ARM: Add optimized ARMv7 strcmp implementation
Add an optimized implementation of strcmp for ARMv7-A cores. This
implementation is significantly faster than the current generic C
implementation, particularly for strings of 16 bytes and longer.

Tested with the glibc string tests for arm-linux-gnueabihf and
armeb-linux-gnueabihf.

The code was written by ARM, who have agreed to assign the copyright
to the FSF for integration into glibc.

7776e6692f Revert incorrect removal of the XDR currency from locale/iso-4217.def
In 7447ccd98e, the XDR currency was
removed from locale/iso-4217.def, despite the fact that it's both
still a part of the standard, according to the official table:

http://www.currency-iso.org/dam/downloads/table_a1.xml

... and, more importantly, is referenced from localedata/i18n, so
any quick-and-dirty locale definition that uses "copy i18n" for
LC_MONETARY wouldn't work anymore.

6d96f5e4c0 ARM: Remove lowlevellock.c
lowlevellock.c for arm differs from the generic lowlevellock.c only in
insignificant ways, so can be removed. Happily, this fixes BZ 15119
(unnecessary busy loop in __lll_timedlock_wait on arm).

The notable differences between the arm and generic implementations are:

1) arm __lll_timedlock_wait has a fast path out if futex has been set
to 0 between since the function was called. This seems unlikely to
happen very often, so it seems at worst harmless to lose this fast
path.

2) Some function in arm's lowlevellock.c set futex to 2 if it was 1.
The generic version always sets the futex to 2. As futex can only be
0, 1 or 2 on entry into these functions, the behaviour is equivalent.
(If the futex manages to be 0 on entry then we've just lost another
unlikely fast path out.)

There are no test suite regressions.

Note that hppa and sparc also have their own lowlevellock.c. I believe
hppa can also be removed, so I'll send a separate patch for that
shortly. sparc's seems to be genuinely needed as it uses a different
locking structure.

Also note that the analysis at
https://sourceware.org/ml/libc-ports/2013-02/msg00021.html indicates a
further locking performance bug to fix - I've got a partial patch for
that which I can submit once I've finished testing.
