commit 1a3fa7988335c0e6a97f7debfc5bf1091c94bd17

sysv: linux: Pass 64-bit version of semctl syscall
The semctl_syscall() function passes a union semun to the kernel. The
union includes struct semid_ds as a member. On 32-bit architectures the
Linux kernel provides a *_high version of the 32-bit sem_otime and
sem_ctime values. These can be combined to get a 64-bit version of the
time.
This patch adjusts the struct semid_ds to support the *_high versions
of sem_otime and sem_ctime. For 32-bit systems with a 64-bit time_t
this can be used to get a 64-bit time from the two 32-bit values.
Due to alignment differences between 64-bit and 32-bit variables we
also need to set nsems to ensure it's correct.

sysv: linux: Add 64-bit time_t variant for shmctl
To provide a y2038 safe interface a new symbol __shmctl64 is added
and __shmctl is change to call it instead (it adds some extra buffer
copy for the 32 bit time_t implementation).
Two two new structures are added:
1. kernel_shmid64_ds: used internally only on 32-bit architectures
to issue the syscall. A handful architectures (hppa, i386, mips,
powerpc32, and sparc32) requires specific implementation due its
specific kernel ABI.
2. shmid_ds64: this is only for __TIMESIZE != 64 to use along with
the 64-bit semctl. It is different than the kernel one because
the exported 64-bit time_t might require different alignment
depending of the architecture ABI.
So the resulting implementation does:
1. For 64-bit architectures it assumes shmid_ds already contains
64-bit time_t fields it will result in just the __shmctl symbol
using the __shmctl64 code. The shmid_ds argument is passed as-is
to the syscall.
2. For 32-bit architectures with default 64-bit time_t (newer ABIs
such riscv32 or arc), it will also result in only one exported
symbol but with the required high/low time handling.
3. Finally for 32-bit architecture with both 32-bit and 64-bit time_t
support we follow the already set way to provide one symbol with
64-bit time_t support and implement the 32-bit time_t support on
basis of the 64-bit one.
The default 32-bit symbol will allocate and copy the shmid_ds
over multiple buffers, but this should be deprecated in favor
of the __shmctl64 anyway.
Checked on i686-linux-gnu and x86_64-linux-gnu. I also did some sniff
tests on powerpc, powerpc64, mips, mips64, armhf, sparcv9, and
sparc64.

sysv: linux: Add 64-bit time_t variant for msgctl
To provide a y2038 safe interface a new symbol __msgctl64 is added
and __msgctl is change to call it instead (it adds some extra buffer
copy for the 32 bit time_t implementation).
Two two new structures are added:
1. kernel_msqid64_ds: used internally only on 32-bit architectures

sysv: linux: Add 64-bit time_t variant for semctl
Different than others 64-bit time_t syscalls, the SysIPC interface
does not provide a new set of syscall for y2038 safeness. Instead it
uses ununsed fields in semid_ds structure the return the high bits for
the timestamps.
To provide a y2038 safe interface a new symbol __semctl64 is added
and __semctl is change to call it instead (it adds some extra buffer
copy for the 32 bit time_t implementation).
Two two new structures are added:
1. kernel_semid64_ds: used internally only on 32-bit architectures
to issue the syscall. A handful architectures (hppa, i386, mips,
powerpc32, sparc32) requires specific implementation due its
specific kernel ABI.
2. semid_ds64: this is only for __TIMESIZE != 64 to use along with
the 64-bit semctl. It is different than the kernel one because
the exported 64-bit time_t might require different alignment
depending of the architecture ABI.
So the resulting implementation does:
1. For 64-bit architectures it assumes semid_ds already contains
64-bit time_t fields it will result in just the __semctl symbol
using the __semctl64 code. The semid_ds argument is passed as-is
to the syscall.
2. For 32-bit architectures with default 64-bit time_t (newer ABIs
such riscv32 or arc), it will also result in only one exported
symbol but with the required high/low handling.
It might be possible to optimize it further to avoid the
kernel_semid64_ds to semun transformation if the exported ABI
for the architectures matches the expected kernel ABI, but the
implementation is already complex enough and don't think this
should be a hotspot in any case.
3. Finally for 32-bit architecture with both 32-bit and 64-bit time_t
support we follow the already set way to provide one symbol with
64-bit time_t support and implement the 32-bit time_t support on
basis of the 64-bit one.
The default 32-bit symbol will allocate and copy the semid_ds

htl: Move cleanup handling to non-private libc-lock
This adds sysdeps/htl/libc-lock.h which augments sysdeps/mach/libc-lock.h with
the htl-aware cleanup handling. Otherwise inclusion of libc-lock.h
without libc-lockP.h would keep only the mach-aware handling.
This also fixes cleanup getting called when the binary is
statically-linked without libpthread.
* sysdeps/htl/libc-lockP.h (__libc_cleanup_region_start,
__libc_cleanup_end, __libc_cleanup_region_end,
__pthread_get_cleanup_stack): Move to...
* sysdeps/htl/libc-lock.h: ... new file.
(__libc_cleanup_region_start): Always set handler and arg.
(__libc_cleanup_end): Always call the cleanup handler.
(__libc_cleanup_push, __libc_cleanup_pop): New macros.

tst-cancel4-common.c: fix calling socketpair
PF_UNIX was actually never intended to be passed as protocol parameter to
socket() calls: it is a protocol family, not a protocol. It happens that
Linux introduced accepting it during its 2.0 development, but it shouldn't.
OpenBSD kernels accept it as well, but FreeBSD and NetBSD rightfully do not.
GNU/Hurd does not either.
* nptl/tst-cancel4-common.c (do_test): Pass 0 instead of PF_UNIX as
protocol.

x86: Detect Intel Advanced Matrix Extensions
Intel Advanced Matrix Extensions (Intel AMX) is a new programming
paradigm consisting of two components: a set of 2-dimensional registers
(tiles) representing sub-arrays from a larger 2-dimensional memory image,
and accelerators able to operate on tiles. Intel AMX is an extensible
architecture. New accelerators can be added and the existing accelerator
may be enhanced to provide higher performance. The initial features are
AMX-BF16, AMX-TILE and AMX-INT8, which are usable only if the operating
system supports both XTILECFG state and XTILEDATA state.
Add AMX-BF16, AMX-TILE and AMX-INT8 support to HAS_CPU_FEATURE and
CPU_FEATURE_USABLE.

S390: Optimize __memset_z196.
It turned out that an 256b-mvc instruction which depends on the
result of a previous 256b-mvc instruction is counterproductive.
Therefore this patch adjusts the 256b-loop by storing the
first byte with stc and setting the remaining 255b with mvc.
Now the 255b-mvc instruction depends on the stc instruction.

S390: Optimize __memcpy_z196.
This patch introduces an extra loop without pfd instructions
as it turned out that the pfd instructions are usefull
for copies >=64KB but are counterproductive for smaller copies.
