41e77f36d4 Fix pread consolidation on ports that require argument alignment
This patch fixes the __ALIGNMENT_{ARG,COUNT} definition for ports that
define __ASSUME_ALIGNED_REGISTER_PAIRS by including the kernel-features.h
(where it is defined if the case).

This was shown on arm with failing cases:

FAIL: debug/tst-chk1
FAIL: debug/tst-chk2
FAIL: debug/tst-chk3
FAIL: debug/tst-chk4
FAIL: debug/tst-chk5
FAIL: debug/tst-chk6

FAIL: debug/tst-lfschk4
FAIL: debug/tst-lfschk5
FAIL: debug/tst-lfschk6
FAIL: posix/tst-preadwrite
FAIL: posix/tst-preadwrite64

The patches fixes it.  Tested on armhf.

	* sysdeps/unix/sysv/linux/sysdep.h: Include kernel-features.h.

b1b8f5d89d Fix strfmon_l: Use specified locale for number formatting [BZ #19633]
The commit 985fc132f2
"strfmon_l: Use specified locale for number formatting [BZ #19633]"
introduced an elf/check-abi-libc testfailure due to __printf_fp_l
on architectures which use sysdeps/ieee754/ldbl-opt/math_ldbl_opt.h.

This patch uses libc_hidden_def instead of ldbl_hidden_def.
The ldbl_strong_alias is removed due to the rename of ___printf_fp_l
to __printf_fp_l.

ChangeLog:

	* stdio-common/printf_fp.c (__printf_fp_l):
	Rename ___printf_fp_l to __printf_fp_l and
	remove strong alias. Use libc_hidden_def instead
	of ldbl_hidden_def macro.

8a727af925 malloc: Remove malloc hooks from fork handler
The fork handler now runs so late that there is no risk anymore that
other fork handlers in the same thread use malloc, so it is no
longer necessary to install malloc hooks which made a subset
of malloc functionality available to the thread that called fork.

29d794863c malloc: Run fork handler as late as possible [BZ #19431]
Previously, a thread M invoking fork would acquire locks in this order:

  (M1) malloc arena locks (in the registered fork handler)
  (M2) libio list lock

A thread F invoking flush (NULL) would acquire locks in this order:

  (F1) libio list lock
  (F2) individual _IO_FILE locks

A thread G running getdelim would use this order:

  (G1) _IO_FILE lock
  (G2) malloc arena lock

After executing (M1), (F1), (G1), none of the threads can make progress.

This commit changes the fork lock order to:

  (M'1) libio list lock
  (M'2) malloc arena locks

It explicitly encodes the lock order in the implementations of fork,
and does not rely on the registration order, thus avoiding the deadlock.

b49ab5f450 Remove union wait [BZ #19613]
The overloading approach in the W* macros was incompatible with
integer expressions of a type different from int.  Applications
using union wait and these macros will have to migrate to the
POSIX-specified int status type.

1c20cb2098 localedata: LC_MEASUREMENT: use copy directives everywhere
There are only two measurement systems that locales use: US and metric.
For the former, move to copying the en_US locale, while for the latter,
move to copying the i18n locale.  This lets us clean up all the stray
comments like FIXME.

There should be no functional differences here.

a057f5f8cd X86-64: Use non-temporal store in memcpy on large data
The large memcpy micro benchmark in glibc shows that there is a
regression with large data on Haswell machine.  non-temporal store in
memcpy on large data can improve performance significantly.  This
patch adds a threshold to use non temporal store which is 6 times of
shared cache size.  When size is above the threshold, non temporal
store will be used, but avoid non-temporal store if there is overlap
between destination and source since destination may be in cache when
source is loaded.

For size below 8 vector register width, we load all data into registers
and store them together.  Only forward and backward loops, which move 4
vector registers at a time, are used to support overlapping addresses.
For forward loop, we load the last 4 vector register width of data and
the first vector register width of data into vector registers before the
loop and store them after the loop.  For backward loop, we load the first
4 vector register width of data and the last vector register width of
data into vector registers before the loop and store them after the loop.

	* sysdeps/x86_64/cacheinfo.c (__x86_shared_non_temporal_threshold):
	New.
	(init_cacheinfo): Set __x86_shared_non_temporal_threshold to 6

b39d84adff VDSO support for MIPS
This patch adds support for using the implementations of gettimeofday()
and clock_gettime() provided by the kernel in the VDSO. The VDSO will
always provide clock_gettime() as CLOCK_{REALTIME,MONOTONIC}_COARSE can
be implemented regardless of platform. CLOCK_{REALTIME,MONOTONIC}, along
with gettimeofday(), are only implemented on platforms which make use of
either the CP0 count or GIC as their clocksource. On other platforms,
the VDSO does not provide the __vdso_gettimeofday symbol, as it is
never useful.

The VDSO functions return ENOSYS when they encounter an unsupported
request, in which case glibc should fall back to the standard syscall.

Tested with upstream kernel 4.5 and QEMU emulating Malta.

./vdsotest gettimeofday bench

071af4769f Consolidate pwrite/pwrite64 implementations
This patch consolidates all the pwrite/pwrite64 implementation for Linux
in only one (sysdeps/unix/sysv/linux/pwrite{64}.c).  It also removes the
syscall from the auto-generation using assembly macros.

For pwrite{64} offset argument placement the new SYSCALL_LL{64} macro
is used.  For pwrite ports that do not define __NR_pwrite will use
__NR_pwrite64 and for pwrite64 ports that dot define __NR_pwrite64 will
use __NR_pwrite for the syscall.

eeddfa91cb Consolidate off_t/off64_t syscall argument passing
This patch add three new macros (SYSCALL_LL, SYSCALL_LL64, and
__ASSUME_WORDSIZE64_ILP32) to use along with off_t and off64_t argument
syscalls.  The rationale for this change is:

1. Remove multiple implementations for the same syscall for different
   architectures (for instance, pread have 6 different implementations).

2. Also remove the requirement to use syscall wrappers for cancellable
   entrypoints.

The macro usage should be used along __ALIGNMENT_ARG to follow ABI constrains
for architecture where it applies.  For instance, pread can be rewritten as:

  return SYSCALL_CANCEL (pread, fd, buf, count,
                         __ALIGNMENT_ARG SYSCALL_LL (offset));

Another macro, SYSCALL_LL64, is provided for off64_t.  The macro
__ASSUME_WORDSIZE64_ILP32 is used by the ABI to define is uses 64-bit register
even if ABI is ILP32 (for instance x32 and mips64-n32).

The changes itself are not currently used in any implementation, so no
code change is expected.

20003c4988 localedata: iw_IL: delete old/deprecated locale [BZ #16137]
From the bug:
Obsolete locale.  The ISO-639 code for Hebrew was changed from 'iw'
to 'he' in 1989, according to Bruno Haible on libc-alpha 2003-09-01.

eb64b6d457 Fix limits.h NL_NMAX namespace (bug 19929).
bits/xopen_lim.h (included by limits.h if __USE_XOPEN) defines
NL_NMAX, but this constant was removed in the 2008 edition of POSIX so
should not be defined in that case.  This patch duly disables that
define for __USE_XOPEN2K8.  It remains enabled for __USE_GNU to avoid
affecting sysconf (_SC_NL_NMAX), the implementation of which uses
"#ifdef NL_NMAX".

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

	[BZ #19929]
	* include/bits/xopen_lim.h (NL_NMAX): Do not define if
	[__USE_XOPEN2K8 && !__USE_GNU].
	* conform/Makefile (test-xfail-XOPEN2K8/limits.h/conform): Remove
	variable.

fb3227b95c Fix termios.h XCASE namespace (bug 19925).
bits/termios.h (various versions under sysdeps/unix/sysv/linux)
defines XCASE if defined __USE_MISC || defined __USE_XOPEN.  This
macro was removed in the 2001 edition of POSIX, and is not otherwise
reserved, so should not be defined for 2001 and later versions of
POSIX.  This patch fixes the conditions accordingly (leaving the macro
defined for __USE_MISC, so still in the default namespace).

Tested for x86_64 and x86 (testsuite, and that installed shared
libraries are unchanged by the patch).

	[BZ #19925]

25dba0ad05 powerpc: Add optimized P8 strspn
This utilizes vectors and bitmasks.  For small needle, large
haystack, the performance improvement is upto 8x.  For short
strings (0-4B), the cost of computing the bitmask dominates,
and is a tad slower.

528ffb3a04 Remove powerpc64 strspn, strcspn, and strpbrk implementation
This patch removes the powerpc64 optimized strspn, strcspn, and
strpbrk assembly implementation now that the default C one
implements the same strategy.  On internal glibc benchtests
current implementations shows similar performance with -O2.

Tested on powerpc64le (POWER8).

282b71f07e Improve generic strpbrk performance
With now a faster strcspn implementation, it is faster to just use
it with some return tests than reimplementing strpbrk itself.
As for strcspn optimization, it is generally at least 10 times faster
than the existing implementation on bench-strspn on a few AArch64
implementations.

Also the string/bits/string2.h inlines make no longer sense, as current
implementation will already implement most of the optimizations.

Tested on x86_64, i386, and aarch64.

	* string/strpbrk.c (strpbrk): Rewrite function.
	* string/bits/string2.h (strpbrk): Use __builtin_strpbrk.
