Linux 6.13 adds four new syscalls. Update syscall-names.list and
regenerate the arch-syscall.h headers with build-many-glibcs.py
update-syscalls.
Tested with build-many-glibcs.py.
Linux 6.11 changes for syscall are:
* fstat/newfstatat for loongarch (it should be safe to add since
255dc1e4ed that undefine them).
* clone3 for nios2, which only adds the entry point but defined
__ARCH_BROKEN_SYS_CLONE3 (the syscall will always return ENOSYS).
* uretprobe for x86_64 and x32.
Update syscall-names.list and regenerate the arch-syscall.h headers

x86/shstk: Enable shadow stacks for x32
1. Add shadow stack support to x32 signal.
2. Use the 64-bit map_shadow_stack syscall for x32.
3. Set up shadow stack for x32.
Add the map_shadow_stack system call to <fixup-asm-unistd.h> and regenerate
arch-syscall.h. Tested on Intel Tiger Lake with CET enabled x32. There
are no regressions with CET enabled x86-64. There are no changes in CET
enabled x86-64 _dl_start_user.

The new tables are currently only used for consistency checks
with the installed kernel headers and the architecture-independent
system call names table. They are based on Linux 5.4.
The goal is to use these architecture-specific tables to ensure
that system call wrappers are available irrespective of the version
of the installed kernel headers.
The tables are formatted in the form of C header files so that they
can be used directly in an #include directive, without external
preprocessing. (External preprocessing of a plain table file
would introduce cross-subdirectory dependency issues.) However,
the intent is that they can still be treated as tables and can be
processed by simple tools.
The irregular system call names on 32-bit arm add a complication.
The <fixup-asm-unistd.h> header is introduced to work around that,
and the system calls are listed under regular names in the
<arch-syscall.h> file.
A make target, update-syscalls-list, is added to patch the glibc
sources with data from the current kernel headers.
