Linux 5.5 has no new syscalls to add to syscall-names.list, but it
does newly enable the clone3 syscall for AArch64. This patch updates
the kernel version listed in syscall-names.list and regenerates the
AArch64 arch-syscall.h.
Tested with build-many-glibcs.py.

Have you been able to use build-many-glibcs.py for the update? Does
the update-syscalls subcommand fit your needs?

I used update-syscalls successfully for the regeneration (I only named
aarch64-linux-gnu on the update-syscalls run since there weren't any new
all-architectures syscalls, so haven't tested the case of an
all-architectures update).

In practice clone3 has also been enabled in Linux 5.4.12. This cause the
misc/tst-glibcsyscalls test to fail when building glibc 2.31 with Linux
kernel headers >= 5.4.12:
original exit status 1
error: kernel syscall 'clone3' (435) not known to glibc
info: glibc tables are based on kernel version 5.4
info: installed kernel headers are version 5.4
Therefore should we backport this commit into the 2.31 stable branch?

Yes, we should. Thanks.
