4d653a59ff Add mmap usage in malloc_info output
The current malloc_info xml output only has information about
allocations on the heap.  Display information about number of mappings
and total mmapped size to this to complete the picture.

1670e207c5 aarch64: Rely on syscalls preserving registers
In several cases we've had asm routines rely on syscalls not clobbering
call-clobbered registers, and that's now deemed ABI.  So take advantage
of this in the INLINE_SYSCALL path as well.

Shrinks libc.so by about 1k.

Delay the use of stat/fstat until stat data is required.  When the
kernel returns ST_VALID, stat data is not used by __internal_statvfs.

36ffe7398a ARM: Fix handling of concurrent TLS descriptor resolution
The current code for handling concurrent resolution says that the
ABI for _dl_tlsdesc_resolve_hold is the same as that of
_dl_tlsdesc_lazy_resolver. However _dl_tlsdesc_resolve_hold is
called from the trampoline directly rather than the lazy resolver
stub so, for example, r2 has not been pushed so does not needed
to be restored.

This fixes an intermittent failure in nptl/tst-tls3 when building
glibc for arm-linux-gnueabihf with -mtls-dialect=gnu2.

ChangeLog:

2014-05-27  Will Newton  <will.newton@linaro.org>

	[BZ #16990]
	* sysdeps/arm/dl-tlsdesc.S (_dl_tlsdesc_resolve_hold): Save
	and restore r2 rather than just restoring.

2482ae433a Fix offset computation for append+ mode on switching from read (BZ #16724)
The offset computation in write mode uses the fact that _IO_read_end
is kept in sync with the external file offset.  This however is not
true when O_APPEND is in effect since switching to write mode ought to
send the external file offset to the end of file without making the
necessary adjustment to _IO_read_end.

Hence in append mode, offset computation when writing should only
consider the effect of unflushed writes, i.e. from _IO_write_base to
_IO_write_ptr.

The wiki has a detailed document that describes the rationale for
offsets returned by ftell in various conditions:

fdfd175d46 Remove nested function mi_arena from malloc_info.
The nested function mi_arena was removed from malloc_info
and made into a non-nested static inline function of the same
name with the correct set of arguments passed from malloc_info.
This enables building glibc with compilers that don't support
nested functions. Future work on malloc_info should remove these
functions entirely to support JSON format output. Therefore we
do the minimum required to remove the nested function.

15eaf6ffe3 benchtests: Add new directive for benchmark initialization hook
Add a new 'init' directive that specifies the name of the function to
call to do function-specific initialization.  This is useful for
benchmarks that need to do a one-time initialization before the
functions are executed.

75f11331f9 [AARCH64] correct alignment of TLS_TCB_ALIGN (BZ #16796)
This fixes a variety of testsuite failures for me:
tststatic.out Error 1
tststatic2.out Error 1
tst-tls9-static.out Error 1
tst-audit8.out Error 127
tst-audit9.out Error 127
tst-audit1.out Error 127
and also has the added benefit of making LD_AUDIT/sotruss work on
AArch64.

Otherwise, we bail out early in _dl_try_allocate_static_tls as the
alignment requirement of the PT_TLS section in libc is 16.

c3ec475c5d Use NSS_STATUS_TRYAGAIN to indicate insufficient buffer (BZ #16878)
The netgroups nss modules in the glibc tree use NSS_STATUS_UNAVAIL
(with errno as ERANGE) when the supplied buffer does not have
sufficient space for the result.  This is wrong, because the canonical
way to indicate insufficient buffer is to set the errno to ERANGE and
the status to NSS_STATUS_TRYAGAIN, as is used by all other modules.

This fixes nscd behaviour when the nss_ldap module returns
NSS_STATUS_TRYAGAIN to indicate that a netgroup entry is too long to
fit into the supplied buffer.

aa2f176d6f arm,aarch64: Remove SINGLE_THREAD_P_PIC
This macro was removed by

but not applied to the (still separate) eabi port so necro'd
when the eabi port superceded the old abi.  It was thence
copied into the new AArch64 port.

e59252a58e Define TSVTX in tar.h for older POSIX (bug 16978).
As noted in bug 16978, older POSIX versions include

in the specified contents of <tar.h>, with only the 2001 edition
introducing the notion of XSI-conditional definitions and conditioning
that definition.  Thus, this macro should be defined for
!__USE_XOPEN2K as well as for __USE_XOPEN, and this patch duly defines
it in that case.  Tested x86_64.

	[BZ #16978]
	* posix/tar.h [!__USE_XOPEN2K] (TSVTX): Define macro.
	* conform/Makefile (test-xfail-POSIX/tar.h/conform): Remove

b72592e75f Fix log10 (1) in round-downward mode (bug 16977).
As with various other issues of this kind, bug 16977 is log10 (1)
wrongly returning -0 rather than +0 in round-downward mode because of
an implementation effectively in terms of log1p (x - 1).  This patch
fixes the issue in the same way used for log.

Tested x86_64 and x86 and ulps updated accordingly.  Also tested for
mips64 to confirm a fix was needed for ldbl-128 and to validate that
fix (also applied to ldbl-128ibm since that version of logl is
essentially the same as the ldbl-128 one).
