771eb1415f nptl: Fix abort in case of set*id failure [BZ #17135]
If a call to the set*id functions fails in a multi-threaded program,
the abort introduced in commit 13f7fe35ae
was triggered.

We address by checking that all calls to set*id on all threads give
the same result, and only abort if we see success followed by failure
(or vice versa).

bc1da1765e PowerPC: Fix build due missing lll_robust_trylock
Commit 887865f remove the lll_robust_trylock definition on all
architectures, however for powerpc both __lll_trylock and
__lll_cond_trylock were based on lll_robust_trylock definition.
This patch restore it with a different name.

Summary of changes:

- Use of !_LIBC instead of HAVE_CONFIG_H
- Code changes in [!_LIBC] that don't affect us
- Minor formatting changes
- Use __builtin_expect in shared code
- Define some macros in [_LIBC] that are used in gnulib but never
  defined in glibc
- Flip macro check for STRERROR_R_CHAR_P so that it does not throw a
  warning

d62aa75af1 Fix crash when system has no ipv6 address [BZ #17125]
Here's an updated patch to fix the crash in bug-ga2 when the system
has no configured ipv6 address.  I have taken a different approach of
using libc_freeres_fn instead of the libc_freeres_ptr since the former
gives better control over what is freed; we need that since cache may
or may not be allocated using malloc.

Verified that bug-ga2 works correctly in both cases and does not have
memory leaks in either of them.

82374e65d7 Fix -Wundef warnings for SHARED
The definition of SHARED is tested with #ifdef pretty much everywhere
apart from these few places. The tlsdesc.c code seems to be copy and
pasted to a few architectures and there is one instance in the hppa
startup code.

6ee3eab429 Fix -Wmaybe-uninitialized warning in xdr.c
While we're at fixing build warnings, here's one unnecessary warning
that can be fixed fairly easily.  The SIZE variable is never actually
use uninitialized, but the compiler cannot make that out and thinks
(correctly) that there is a potential for accessing SIZE without
initializing it.  Make this safe by initializing SIZE to 0.

Tested on x86_64.

e35c53e397 Check value at resplen2 if it is not NULL
There was a typo in the previous patch due to which resplen2 was
checked for non-zero instead of the value at resplen2.  Fix that and
improve the condition by checking resplen2 for non-NULL (instead of
answerp2) and also adding the check in a third place.

87868c2418 PowerPC: Align power7 memcpy using VSX to quadword
This patch changes power7 memcpy to use VSX instructions only when
memory is aligned to quardword.  It is to avoid unaligned kernel traps
on non-cacheable memory (for instance, memory-mapped I/O).

17762f6625 PowerPC: optimized memmove for POWER7/PPC64
This patch adds an optimized memmove optimization for POWER7/powerpc64.
Basically the idea is to use the memcpy for POWER7 on non-overlapped
memory regions and a optimized backward memcpy for memory regions
that overlap (similar to the idea of string/memmove.c).

The backward memcpy algorithm used is similar the one use for memcpy for
POWER7, with adjustments done for alignment.  The difference is memory
is always aligned to 16 bytes before using VSX/altivec instructions.

d6f68bbef4 PowerPC: memmove default implementation cleanup
This patch removes the powerpc specific logic in memmove and instead
include default implementation with MEMCPY_OK_FOR_FWD_MEMMOVE defined.
This lead in a increase performance, since the constraints to use
memcpy in powerpc code are too restrictive and memcpy can be used for
any forward memmove.

1570a72bb8 string/memchr.c: Merge from gnulib
Merge most of the gnulib implementation of memchr. The changes that
remain are:

 - copyright header
 - bp-sym.h removed
 - reg_char removed
 - allow MEMCHR to be redefined
 - non-conforming whitespace changes

The merged code fixes a number of -Wundef warnings and also introduces
an optimized algorithm. I haven't detected any performance difference
in the new code which I believe is down to the quite specific
circumstances required to hit it. However the new code is approximately
half the size of the old code on AArch64 (which uses generic memchr).

ChangeLog:

2014-07-04  Will Newton  <will.newton@linaro.org>

	* string/memchr.c: Merge from gnulib.
	[_LIBC]: Remove conditionals.
	(__ptr_t): Remove define.
	(LONG_MAX_32_BITS): Likewise.
	(LONG_MAX): Likewise.
	(MEMCHR): Use ANSI prototype and optimize algorithm.
