I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

This reverts commit 20b39d59467b0c1d858e89ded8b0cebe55e22f60 to move
{f}xstat{at} back to default symbols. ABIs with default symbol version
of 2.33 or newer (such as riscv32) continue to just provide the stat
symbols.
The idea is to not force static libraries built against old glibc
to update against new glibcs (since they reference the old
{f}xstat{at} symbols).
Checked on x86_64-linux-gnu and i686-linux-gnu.

They are no interna uses anymore. The riscv32 ABI was added on 2.33,
so it is safe to remove the old __{f,l}stat{at} symbols and just
provide the newer {f,l}stat{at} ones.
Checked with a build for all affected ABIs. I also checked on x86_64,
i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.

It implements all the required syscall for the all Linux kABIS on
fstatat{64} instead of calling fxstatat{64}.
On non-LFS implementation, it handles 3 cases:
1. New kABIs which uses generic pre 64-bit time Linux ABI (csky and
nios): it issues __NR_fstat64 plus handle the overflow on st_ino,
st_size, or st_blocks.
2. Old KABIs with old non-LFS support (arm, i386, hppa, m68k,
microblaze, mips32, s390, sh, powerpc, and sparc32): it issues
__NR_fstatat64 and convert the result to struct stat.
3. 64-bit kABI outliers (mips64 and mips64-n32): it issues
__NR_newfstatat and convert the result to struct stat.
The generic LFS implementation handles multiple cases:
1. XSTAT_IS_XSTAT64 being 1:
1.1. 64-bit kABI (aarch64, ia64, powerpc64*, s390x, riscv64, and
x86_64): it issues __NR_newfstatat.
1.2. 64-bit kABI outlier (alpha): it issues __NR_fstatat64.
1.3. 64-bit kABI outlier where struct stat64 does not match kernel
one (sparc64): it issues __NR_fstatat64 and convert the result
to struct stat64.
1.4. 32-bit kABI with default 64-bit time_t (arc, riscv32): it
issues __NR_statx and convert the result to struct stat64.
2. Old ABIs with XSTAT_IS_XSTAT64 being 0:
2.1. All kABIs with non-LFS support (arm, csky, i386, hppa, m68k,
microblaze, nios2, sh, powerpc32, and sparc32): it issues
__NR_fstatat64.
2.2. 64-bit kABI outliers (mips64 and mips64-n32): it issues
__NR_newfstatat and convert the result to struct stat64.
It allows to remove all the hidden definitions from the {f,l}xstat{64}
(some are still kept because Hurd requires it).
Checked with a build for all affected ABIs. I also checked on x86_64,
i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.

The LFS support is implemented on fxstat64.c, instead of fxstat.c for
64-bit architectures. The fxstat.c implements the non-LFS and it is
a no-op for !XSTAT_IS_XSTAT64.
The generic non-LFS implementation handles two cases:
1. New kABIs which uses generic pre 64-bit time Linux ABI (csky and
nios): it issuess __NR_fstat64 plus handle the overflow on st_ino,
st_size, or st_blocks. It only handles _STAT_VER_KERNEL.
2. Old KABIs with old non-LFS support (arm, i386, hppa, m68k,
microblaze, s390, sh, powerpc, and sparc32). For _STAT_VER_KERNEL
it issues __NR_fstat, otherwise it calls __NR_fstat64 and convert
to non-LFS stat struct and handle possible overflows on st_ino,
st_size, or st_blocks.
Also non-LFS mips is an outlier and it has its own implementation since
_STAT_VER_LINUX requires a different conversion function (it uses the
kernel_stat as the sysissues argument since its exported ABI is
different than the kernel one for both non-LFS and LFS implementation).
The generic LFS implementation handles multiple cases:
1. XSTAT_IS_XSTAT64 being 1:
1.1. 64-bit kABI (aarch64, ia64, powerpc64*, s390x, riscv64, and
x86_64): it issuess __NR_fstat for _STAT_VER_KERNEL or
_STAT_VER_LINUX.
1.2. Old 64-bit kABI with defines __NR_fstat64 instead of __NR_fstat
(sparc64): it issues __NR_fstat for _STAT_VER_KERNEL or
__NR_fstat64 and convert to struct stat64.
1.3. New 32-bit kABIs with only 64-bit time_t support (arc and
riscv32): it issuess __NR_statx and covert to struct stat64.
2. Old ABIs with XSTAT_IS_XSTAT64 being 0 (arm, csky, i386, hppa,
m68k, microblaze, mips32, nios2, sh, powerpc32, and sparc32): it
issues __NR_fstat64.
Also, two special cases requires specific implementations:
1. alpha: it requires to handle _STAT_VER_KERNEL64 to issues
__NR_fstat64 and use the kernel_stat with __NR_fstat otherwise.
2. mips64: as for non-LFS implementation its ABIs differ from
glibc exported one, which requires an specific conversion
function to handle the kernel_stat.
Checked with a build for all affected ABIs. I also checked on x86_64,
i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.

Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:

I've moved the MIPS port from ports to the main sysdeps hierarchy.
Beyond the README update, the move of the files was simply
git mv ports/sysdeps/mips sysdeps/mips
git mv ports/sysdeps/unix/mips sysdeps/unix/mips
git mv ports/sysdeps/unix/sysv/linux/mips sysdeps/unix/sysv/linux/mips
and in addition to the ChangeLog entries here, I put a note at the top
of ports/ChangeLog.mips similar to those in other files.
Tested that disassembly of installed shared libraries for mips is the
same before and after this patch (except for ld.so where paths in
assertions are involved, as for arm).
* sysdeps/mips: Move directory from ports/sysdeps/mips.
