I noticed I already applied the patch last week to the asm-generic cleanups
branch, but forgot to send out the email about it.

I do agree the file names are rather useless, and I would apply a follow-up
patch to completely remove them as well. My real plan was to remove
the file itself and replace it with the parsable syscall.tbl format that we
use for all non-generic architectures, but I haven't gotten around to updating
the patch that Firoz Khan did a long time ago.
