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

commit 16751c0ac4efaf1cefd793a79c469f9d62ddb3ed
Author: Jason A. Donenfeld <Jason@xxxxxxxxx>

    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.
