Fix tst-sscanf and tst-swscanf on 64-bit.

	* stdio-common/tst-sscanf.c (main): Use 'long' for 'dummy' when
	processing int_tests.
malloc/mtrace.c: Cosmetic cleanup.

Remove an unused #define and use ANSI prototypes.

Generated code identical on x86_64-unknown-linux-gnu.

ChangeLog:

2014-02-11  Will Newton  <will.newton@linaro.org>

	* malloc/mtrace.c (attribute_hidden): Remove unused macro
	definition.  (tr_where, tr_freehook, tr_mallochook,
	tr_reallochook, tr_memalignhook): Use ANSI protoype.
include/stap-probe.h: Add comment about SystemTap argument format

Add a comment pointing to the SystemTap wiki page that documents the
format of the arguments. Also add a pointer to the SystemTap and
gdb sources which seem to be the best place to get the architecture
specific details.

ChangeLog:

2014-02-11  Will Newton  <will.newton@linaro.org>

	* include/stap-probe.h: Add comment about probe argument
	format.
manual/probes.texi: Add documentation of setjmp/longjmp probes

Add some documentation of the setjmp, longjmp and longjmp_target
Systemtap probe points.

ChangeLog:

	* manual/probes.texi (Internal Probes): Add documentation
	of setjmp, longjmp and longjmp_target probes.
manual/probes.texi: Use "triggered" instead of "hit"

Use the term "triggered" instead of "hit" when talking about probe
points.

	* manual/probes.texi (Mathematical Function Probes): Use

Relocate AArch64 from ports to libc.

This patch moves the AArch64 port to the main sysdeps hierarchy.  The
move is essentially:

  git mv ports/sysdeps/aarch64 sysdeps/aarch64
  git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64

The README is updated and I've updated ChangeLog.aarch64 along the
lines of the ARM move.  The AArch64 build has been tested to confirm
that there were no changes in objdump -dr output or the shared
objects.
Remove unused variable from stdlib/setenv.c
BZ #16447: Fix ldbl-128 expl implementation.

Extend the range of numbers handled via unsafe mode.
Add expl testcase and regenerate ULPs for s390.
Merge MIPS dl-lookup.c into generic file.

MIPS has its own version of dl-lookup.c to deal with differences
between undefined symbol semantics in the PIC and non-PIC ABIs.  This
is often liable to get out of date with respect to the generic file
(for example, the recent __builtin_expect changes didn't cover ports,
and it's not obvious to anyone changing dl-lookup.c that there would
be architecture-specific versions).

This patch adds a macro that dl-machine.h can define that is used in
the appropriate place in dl-lookup.c, so that MIPS no longer needs its
own version of that file.

Tested for mips64 that the only changes to disassembly of installed
shared libraries appear to be ld.so changes attributable to different
line numbers and paths in assertions.

	* elf/dl-lookup.c (ELF_MACHINE_SYM_NO_MATCH): Define if not
	already defined.
	(do_lookup_x): Use ELF_MACHINE_SYM_NO_MATCH.
	* sysdeps/mips/dl-lookup.c: Remove.
	* sysdeps/mips/dl-machine.h (ELF_MACHINE_SYM_NO_MATCH): New macro.
Regenerate x86_64 ulps.
Remove _BSD_SOURCE and _SVID_SOURCE.

This is a minimal patch to remove _BSD_SOURCE and _SVID_SOURCE from
the documented user API, making them into aliases for _DEFAULT_SOURCE
with a #warning given, but keeping most of the features.h logic using
those macros and all the exising __USE_* conditionals, on the basis
that all the consequent cleanups will go in followup patches.

Tested x86_64.

	* include/features.h: Update comment documenting feature test
	macros.
	[_BSD_SOURCE || _SVID_SOURCE]: Give #warning.  Define
	_DEFAULT_SOURCE.
	* manual/creature.texi (_BSD_SOURCE): Remove documentation.
	(_SVID_SOURCE): Likewise.
	(_DEFAULT_SOURCE): Update description of default features.
	(Feature Test Macros): Don't mention _SVID_SOURCE in conjunction
	with _GNU_SOURCE.
	* manual/filesys.texi (__ftw_func_t): Do not refer to _BSD_SOURCE.
	(S_ISVTX): Likewise.
	* manual/math.texi (Mathematical Constants): Likewise.
	* manual/signal.texi (Interrupted Primitives): Likewise.
	* manual/startup.texi (putenv): Do not refer to _SVID_SOURCE.
	* math/test-matherr.c (_SVID_SOURCE): Do not define.
	* sysvipc/sys/ipc.h [__USE_SVID && !__USE_XOPEN && __GNUC__ >= 2]:
	Don't refer to _SVID_SOURCE in warning text.
