[PATCH RFC 0/1] UAPI,x86: export syscall numbers for all x86 archs

[David Drysdale <drysdale@google.com>]

A while ago I was trying to build a seccomp-bpf filter program that would
survive a change of x86 architecture.  This was complicated for all sorts of
reasons, but one of the problems was that the different syscall numbers aren't
all available at the same time -- hence this patch.

Naming-wise, Andy Lutomirski has indicated he'd prefer the prefixes to be
__NR_x86_64_, __NR_x86_64_x32_ and __NR_i386_; however, for the latter two
sets of numbers there are existing headers that use different prefixes
(__NR_x32_ and __NR_ia32_), so altering those would involve a change and/or an
additional set of definitions.  For the new constants I've left in my
original suggestion (__NR_amd64_) for the time being.

What are folks' thoughts about the preferred naming for these?
