6b33f373c7 arm: Remove ioperm/iopl/inb/inw/inl/outb/outw/outl support
Linux only supports the required ISA sysctls on StrongARM devices,
which are armv4 and no longer tested during glibc development
and probably bit-rotted by this point.  (No reported test results,
and the last discussion of armv4 support was in the glibc 2.19
release notes.)

0bb8f8c791 Linux: Add oddly-named arm syscalls to syscall-names.list
<asm/unistd.h> on arm defines the following macros:

#define __ARM_NR_breakpoint             (__ARM_NR_BASE+1)
#define __ARM_NR_cacheflush             (__ARM_NR_BASE+2)
#define __ARM_NR_usr26                  (__ARM_NR_BASE+3)

#define __ARM_NR_get_tls                (__ARM_NR_BASE+6)

These do not follow the regular __NR_* naming convention and
have so far been ignored by the syscall-names.list consistency
checks.  This commit adds these names to the file, preparing
for the availability of these names in the regular __NR_*
namespace.

9250e6610f powerpc: Fix build failures with current GCC
Since GCC commit 271500 (svn), also known as the following commit on the
git mirror:

commit 61edec870f9fdfb5df3fa4e40f28cbaede28a5b1

    [RS6000] Don't pass -many to the assembler

glibc builds are failing when an assembly implementation does not
declare the correct '.machine' directive, or when no such directive is
declared at all.  For example, when a POWER6 instruction is used, but
'.machine power6' is not declared, the assembler will fail with an error
similar to the following:

    ../sysdeps/powerpc/powerpc64/power8/strcmp.S: Assembler messages:
     24 ../sysdeps/powerpc/powerpc64/power8/strcmp.S:55: Error: unrecognized opcode: `cmpb'

This patch adds '.machine powerN' directives where none existed, as well
as it updates '.machine power7' directives on POWER8 files, because the
minimum binutils version required to build glibc (binutils 2.25) now
provides this machine version.  It also adds '-many' to the assembler
command used to build tst-set_ppr.c.

Tested for powerpc, powerpc64, and powerpc64le, as well as with
build-many-glibcs.py for powerpc targets.

Remove support for PowerPC SPE extension (powerpc*-*-*gnuspe*).
GCC 9 dropped support for the SPE extensions to PowerPC, which means
powerpc*-*-*gnuspe* configurations are no longer buildable with that
compiler.  This ISA extension was peculiar to the “e500” line of
embedded PowerPC chips, which, as far as I can tell, are no longer
being manufactured, so I think we should follow suit.

This patch was developed by grepping for “e500”, “__SPE__”, and
“__NO_FPRS__”, and may not eliminate every vestige of SPE support.
Most uses of __NO_FPRS__ are left alone, as they are relevant to
normal embedded PowerPC with soft-float.

09e1b0e3f6 libio: Remove codecvt vtable [BZ #24588]

GCC 3.0, after a C++ ABI bump, so there is no compatibility
requirement with libstdc++.

This change removes several unmangled function pointers which could
be used with a corrupted FILE object to redirect execution.  (libio
vtable verification did not cover the codecvt vtable.)

called when resources are needed using __libc_once (once, init) where
once is a __libc_once_define (static, once) in the dlerror.c file.
Trying to free those resources if init () hasn't been called will
produce errors under valgrind memcheck. So guard the freeing of those
resources using __libc_once_get (once) and make sure we have a valid
key. Also add a similar guard to __dlerror ().

91f043ae84 Make --bindir effective
This allows sets a path using --bindir.  Checked on x86_64-linux-gnu
with a non-default --bindir and checked resulting installed binaries
(pldd for instance).

	* config.make.in (bindir): New variable.

c50e1c263e x86: Remove arch-specific low level lock implementation
This patch removes the arch-specific x86 assembly implementation for
low level locking and consolidate both 64 bits and 32 bits in a
single implementation.

Different than other architectures, x86 lll_trylock, lll_lock, and
lll_unlock implements a single-thread optimization to avoid atomic
operation, using cmpxchgl instead.  This patch implements by using
the new single-thread.h definitions in a generic way, although using
the previous semantic.

The lll_cond_trylock, lll_cond_lock, and lll_timedlock just use
atomic operations plus calls to lll_lock_wait*.

For __lll_lock_wait_private and __lll_lock_wait the generic implemtation
there is no indication that assembly implementation is required
performance-wise.

Checked on x86_64-linux-gnu and i686-linux-gnu.

	* sysdeps/nptl/lowlevellock.h (__lll_trylock): New macro.
	(lll_trylock): Call __lll_trylock.
