It's been repported that __NR_newfstatat has gone missing from the UAPI
headers.
[sanitizer] __NR_newfstatat not defined in linux kernel headers in
aarch64
<https://github.com/llvm/llvm-project/issues/100098>
__NR_newfstatat no longer defined on aarch64
<https://bugzilla.redhat.com/show_bug.cgi?id=2301919>
I suspect that's related to the syscall.tbl refactoring around these
commits:

It has actually been wrongly renamed to __NR_fstatat.

Ah, I see what happened now, this was part of a semi-automated
conversion from the old format and I incorrectly split up the
entries between 32-bit and 64-bit.
There is another bug in the same entry, since in the meantime,
we have also decided to make newfstat/newfstatat unconditional
again for all 64-bit architectures, and this hasn't made it into
the new syscall.tbl format. This one is only important for
loongarch64.
I'll fix up both ASAP, thanks a lot for the report!
