Albanian locale uses the 12-hour clock but some time formats did not
use any AM/PM indicator making the time ambiguous. This commit adds
"%p" wherever it was missing.
It also sets the correct date format because the old "%Y-%b-%d" produced
rather weird results like "2018-Sht-28".
All time formats come from CLDR but as few changes have been introduced
by this commit as possible. Some articles from MSDN and other available
online sources have been also taken into account.

The recent difftime changes introduced localplt test failures on nios2
and sparc32, two configurations where some soft-fp functions are
defined in / exported from libc.so, and where the difftime changes
affected the particular set of floating-point operations used in
libc.so. This patch adds those functions to localplt.data, alongside
other such functions already there. (In the sparc32 case, and more
generally on any platform where long double is a software
floating-point type, it would probably be more efficient to avoid
using long double at all in difftime, but that's a pre-existing
issue.)
Tested with build-many-glibcs.py for its nios2 and sparcv9
configurations.
[BZ #24023]
* sysdeps/unix/sysv/linux/nios2/localplt.data: Allow __floatundidf
PLT reference in libc.so.

_Q_lltoq and _Q_qtod PLT references in libc.so.
This patch updates longlong.h from GCC. There were no local changes
in glibc (the previous version was identical to the r232143 GCC
version, apart from copyright dates which had been updated in both
places), so this patch makes it identical to the version in GCC again.
Tested for x86_64 and x86. Also tested with build-many-glibcs.py for
its RISC-V configurations, as the glibc architecture with the most
substantial changes in longlong.h in this patch.
* stdlib/longlong.h: Update from GCC.
We know that building glibc with GCC 4.9 is broken on various
platforms (bug 23993). As it's more than a year since we last
increased the minimum GCC version to build glibc, this patch changes
the requirement to be GCC 5 or later (indeed, based on 4.9 having been
required for building 2.26, it would be consistent in terms of timing
to require GCC 6 or later from the 2.30 release onwards). It
deliberately just updates the configure test and corresponding
documentation, leaving removal of no-longer-needed __GNUC_PREREQ tests
for a separate patch.
In the NEWS entry, the requirement for a newer GCC version for
powerpc64le is reiterated (as in the entry for the 4.9 requirement in
2.26) to avoid suggesting the version requirement there has gone down.
(If that version goes up further as part of support for binary128 long
double, of course the wording would change at that time.)
Tested for x86_64.
[BZ #23993]

Provide a 64-bit-time version of __difftime (but do not assume
__time64_t is a signed int so that Gnulib can reuse the code)
and make the 32-bit version a wrapper of it.
Current difftime expects two time_t arguments and returns a
double. To preserve source-code compatibility, its 64-bit-time
equivalent expects two __time64_t arguments but still returns
a double.
This patch was tested by running 'make check' on branch
master then applying this patch and its two predecessors and
running 'make check' again, and checking that both 'make check'
yield identical results. This was done on x86_64-linux-gnu and
i686-linux-gnu.
This patch was also functionally tested with an ad hoc userland
C program which checks the result of difftime for various pairs
of 32-bit and, for 64-bit builds, of 64-bit time_t values too.
The program was built and run against a glibc with and without
the patch, and the results compared to ensure the patch does
not change the behavior of difftime.
* include/time.h (__difftime64): Add.
* time/difftime.c (subtract): convert to 64-bit time.
* time/difftime.c (__difftime64): Add.
* time/difftime.c (__difftime): Wrap around __difftime64.
After previous cleanups, the only code in the x86 bits/mathinline.h
that is relevant with current compilers is the inline of
__ieee754_atan2l that is conditional on __LIBC_INTERNAL_MATH_INLINES
(i.e. for when libm itself is being built).
This inline is something that does belong in glibc not GCC, since
__ieee754_atan2l is a purely internal function name. This patch moves
that inline to a new sysdeps/x86/fpu/math_private.h, removing the
bits/mathinline.h header.
Note that previously the inline was only for non-SSE 32-bit x86. That
condition does not make sense, however, for a long double function; if
it's not inlined, exactly the same x87 instruction will end up getting
used by the out-of-line function, for both 32-bit and 64-bit. So that
condition is not retained in the new version.
Tested for x86_64 and x86. As expected, installed stripped shared
libraries are unchanged for 32-bit x86, but installed stripped libm.so
is changed for x86_64 because calls to __ieee754_atan2l start being
inlined where previously they were out of line calls. (The same
change to start inlining the function would presumably also apply for
32-bit built with -mfpmath=sse, but that's not a configuration I've
tested.)
* sysdeps/x86/fpu/math_private.h: New file.
* sysdeps/x86/fpu/bits/mathinline.h: Remove.
Continuing the removal of bits/mathinline.h inlines that would better
be done by the compiler, this patch removes x86 inlines for sinh, cosh
and tanh functions (inlines only previously present for fast-math,
non-SSE 32-bit x86). I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88556> for adding such
inlines as an optimization in GCC.
I believe the only remaining part of the x86 bits/mathinline.h that
does anything useful with current compilers after this patch is the
__LIBC_INTERNAL_MATH_INLINES inline of __ieee754_atan2l; I intend to
remove the whole header and move that inline to a sysdeps
math_private.h header in a subsequent patch.
Tested for x86_64 and x86.
* sysdeps/x86/fpu/bits/mathinline.h (sinh): Remove inline
definition.
(cosh): Likewise.
(tanh): Likewise.

AT_L*_CACHEGEOMETRY is treated in order to specify the cache line size
and its associativity.
Example output from a POWER8:
AT_L1I_CACHESIZE: 32768
AT_L1I_CACHEGEOMETRY: 128B line size, 8-way set associative
AT_L1D_CACHESIZE: 65536

AT_L3_CACHESIZE: 8388608
AT_L3_CACHEGEOMETRY: 128B line size, 8-way set associative
Some of the new types are longer than the previous ones, requiring to
increase the indentation in order to keep the values aligned.

Alpha rt_sigaction syscall uses a slight different kernel ABI than
generic one:
arch/alpha/kernel/signal.c
90 SYSCALL_DEFINE5(rt_sigaction, int, sig, const struct sigaction __user *, act,
91 struct sigaction __user *, oact,
92 size_t, sigsetsize, void __user *, restorer)
Similar as sparc, the syscall expects a restorer function. However
different than sparc, alpha defines the restorer as the 5th argument
(sparc defines as the 4th).
This patch removes the arch-specific alpha sigaction implementation,
adapt the Linux generic one to different restore placements (through
STUB macro), and make alpha use the Linux generic kernel_sigaction
definition.
Checked on alpha-linux-gnu and x86_64-linux-gnu (for sanity).

Commit b4a5d26d88 (linux: Consolidate sigaction implementation) added
a wrong kernel_sigaction definition for m68k, meant for __NR_sigaction
instead of __NR_rt_sigaction as used on generic Linux sigaction
implementation. This patch fixes it by using the Linux generic
definition meant for the RT kernel ABI.
Checked the signal tests on emulated m68-linux-gnu (Aranym). It fixes
the faulty signal/tst-sigaction and man works as expected.

kernel-features.h has a macro __ASSUME_ST_INO_64_BIT, with a comment
"However, SH is lame, and still does not have a 64-bit inode field.".
The macro is, in fact, defined to 0 by Alpha as well as SH. The Alpha
case is, however, trivially useless: none of the files that test
__ASSUME_ST_INO_64_BIT are built for Alpha (which gained kernel
support for stat64 syscalls, with a 64-bit st_ino field, in Linux
2.6.4; the define to 0 for Alpha in glibc predates that).
The SH kernel gained support for a 64-bit st_ino in struct stat64 in
commit 760bcb1deec13c50e20399c84cb6a8ea41cc2820 ("sh: Fix fstatat64()
syscall."), which is in Linux 2.6.22 and later. So the redefinition
of __ASSUME_ST_INO_64_BIT to 0 is of no use for SH either; three of
the files testing it do so immediately after a stat64-family syscall
has been used, which will always have set the 64-bit st_ino correctly
(in addition to the 32-bit __st_ino), while the relevant code
__xstat32_conv executes only after such a syscall in the function
calling __xstat32_conv.
Thus this patch removes __ASSUME_ST_INO_64_BIT and code testing it.
Removing the useless [!__ASSUME_ST_INO_64_BIT] code in __xstat32_conv
renders the [_HAVE_STAT64___ST_INO] and [!_HAVE_STAT64___ST_INO] cases
around it identical, so that conditional is also removed.
Tested compilation with build-many-glibcs.py for its Alpha and SH
configurations; also ran the glibc testsuite for x86_64 and x86.

The ifunc macros s390_vx_libc* are no longer used and

The ifunc handling for wcsspn is adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.
Unfortunately the c ifunc variant can't be omitted at all as it is used
by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned.
