I've had another look at the kernel patch. It basically
looks all good, but the system call table appears to
diverge from the x86_64 list for no (documented) reason,
in the calls above 302. Is that intentional?

I can see why you might want to keep the numbers identical,
but if they are already different, why not use the generic
system call table from asm-generic/unistd.h for the new
ABI?
