sys/ptrace.h on S390 used to be includible both before and after
asm/ptrace.h, until commit b08a6a0dea
among other changes introduced PTRACE_SINGLEBLOCK enum constant which
is also defined in asm/ptrace.h as a macro, making sys/ptrace.h fail
to compile when included after asm/ptrace.h.
* sysdeps/unix/sysv/linux/s390/sys/ptrace.h [_LINUX_PTRACE_H ||
_S390_PTRACE_H]: Undefine all PTRACE_* macro constants defined
later as enum constants, except PTRACE_PEEKUSER, PTRACE_POKEUSER,
and PTRACE_SEIZE_DEVEL that are not defined by Linux headers.
After the recent update of int_select the comment needed an update, too.
While at this, all comments in LC_TELEPHONE were moved above their
respective values because this looks better. Some minor typos fixed.
[BZ #21783]
* localedata/locales/lg_UG (LC_TELEPHONE): Move all comments
above the values, correct some of them.
This patch fixes the argument passing for exit syscall after
the clone function returns on hppa. This fixes misc/tst-clone2
on alpha-linux-gnu.
Checked misc/tst-clone2 on alpha-linux-gnu.
[BZ #21512]
* sysdeps/unix/sysv/linux/alpha/clone.S (__clone): Fix argument
passing to syscall exit.
Since there are no multiarch versions of memmove_chk and memset_chk,
test multiarch versions of memmove_chk and memset_chk only in libc.so.
[BZ #21741]
* sysdeps/i386/i686/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Test memmove_chk and memset_chk only
in libc.so.

PLT avoidance for __stack_chk_fail [BZ #7065]
Add a hidden __stack_chk_fail_local alias to libc.so,
and make sure that on targets which use __stack_chk_fail,
this does not introduce a local PLT reference into libc.so.
which unconditionally added
strong_alias (__stack_chk_fail, __stack_chk_fail_local)
defines __stack_chk_fail_local as an alias of __stack_chk_fail in libc.a.
There is no need to add stack_chk_fail_local.o to libc.a. We only need
to add stack_chk_fail_local.oS to libc_nonshared.a.
Tested on x86-64:
[hjl@gnu-skl-1 build-x86_64-linux]$ nm libc.a | grep __stack_chk_fail
0000000000000000 T __stack_chk_fail
0000000000000000 T __stack_chk_fail_local
[hjl@gnu-skl-1 build-x86_64-linux]$ nm libc_nonshared.a | grep __stack_chk_fail_local
0000000000000000 T __stack_chk_fail_local
[hjl@gnu-skl-1 build-x86_64-linux]$
[BZ #21740]
* debug/Makefile (elide-routines.o): New.
The patch proposed by Peter Bergner [1] to libgcc in order to fix
[BZ #21707] adds a dependency on a symbol provided by the loader,
forcing the loader to be linked to tests after libgcc was linked.
It also requires to read the thread pointer during IRELA relocations.
Tested on powerpc, powerpc64, powerpc64le, s390x and x86_64.

[BZ #21707]
* csu/libc-start.c (LIBC_START_MAIN): Perform IREL{,A}
relocations before or after initializing the TCB on statically
linked executables. That's a per-architecture definition.
* elf/rtld.c (dl_main): Add a comment about thread-local
variables initialization.
* sysdeps/generic/libc-start.h: New file. Define
ARCH_APPLY_IREL and ARCH_SETUP_IREL.
* sysdeps/powerpc/Makefile:
[$(subdir) = elf && $(multi-arch) != no] (tests-static-internal): Add tst-tlsifunc-static.
[$(subdir) = elf && $(multi-arch) != no && $(build-shared) == yes]
(tests-internal): Add tst-tlsifunc.

* sysdeps/powerpc/powerpc64le/Makefile (f128-loader-link): New
variable.
[$(subdir) = math] (test-float128% test-ifloat128%): Force
linking to the loader after linking to libgcc.

Checked misc/tst-clone2 on hppa-linux-gnu.
[BZ #21512]
* sysdeps/unix/sysv/linux/hppa/clone.S (__clone): Fix argument
passing to syscall exit.
This patch adds the HWCAP_JSCVT, HWCAP_FCMA and HWCAP_LRCPC macros
from Linux 4.12 to the AArch64 bits/hwcap.h.
* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_FCMA): New macro.
(HWCAP_JSCVT, HWCAP_LRCPC): Likewise.
Single thread optimization is valid if at thread creation time the
optimization can be disabled. This is in principle true for all
stream objects that user code can access (and thus needs locking),
using the same internal list as fflush(0) uses. However in glibc
open_memstream is not on that list (BZ 21735) so the optimization
has to be disabled.
* libio/memstream.c (__open_memstream): Set _IO_FLAGS2_NEED_LOCK.
* libio/wmemstream.c (open_wmemstream): Likewise.
* nptl/tst-memstream.c: New.
