Since v5, I've split the patches into smaller pieces, and done
a few more syscalls.  But I've also been approaching them in a
more "systematic" way -- taking from the top of the switch.

I've been trying to fix up checkpatch failures as I've moved
code, but I've surely missed some.  I've also been trying to
share code between the "*at" syscalls and their original.

I've tested x86_64->armhf and aarch64->i386 vs LTP.

FYI, as measured by the line count of do_syscall1, this is
about 25% of the total job to be done.

PS: Patch 2/49 is a debugging patch I forgot to remove.
Rather than regenerate the series, I just omitted it here.
