From: Andrea Cervesato <andrea.cervesato@suse.com>
Do not filter out sys_ni_syscall from tables and seed syscall names
from generic headers and existing tables so legacy syscalls like
_sysctl and timerfd are preserved.
Check s390 header macros to detect 31-bit ABI availability instead of
overwriting s390.in with 64-bit definitions on newer kernels.
Fail immediately when compilation fails for a supported architecture
rather than silently continuing.
Fixes: 1694fd203cf1 ("Add script to generate arch(s) dependant syscalls")

To: Linux Test Project
From: Andrea Cervesato <andrea.cervesato@suse.com>
Update architecture syscall tables up to Linux v7.3-rc5 using the
updated generate_arch.sh script. This adds clone3 on sparc/sparc64,
uprobe on x86_64, and new generic syscalls (listns, rseq_slice_yield,
fchroot), while preserving legacy syscall numbers.
