Alright, so, it's looking like this now:

commit 16751c0ac4efaf1cefd793a79c469f9d62ddb3ed
Author: Jason A. Donenfeld <Jason@zx2c4.com>
Date: Mon Nov 28 21:37:14 2022

arch: allocate vgetrandom_alloc() syscall number

Add vgetrandom_alloc() as syscall 451 (or 561 on alpha) by adding it to
all of the various syscall.tbl an unistd.h files.
