That's more or less how v7 was, but Thomas thought the x86 stuff should
be separate. So for v8, the organization is:

1) generic syscall
2) generic vdso
3) x86 wiring

The primary advantage is that future archs wanting to add this now can
just look at commit (3) only, and make a similar commit for that new
arch.

If you think a different organization outweighs that advantage, can you
spell out what division of patches you want, and I'll do that for v9?
Or maybe this v8 is okay?

My interest is that at the end of the series, all architectures
are hooked up with the same syscall number, which avoids confusion
and merge conflicts when we add the next syscall to all tables.

How about one patch to add all the syscall table entries, and then
have the x86 specific change just turn on the Kconfig symbol that
actually enables the syscall?
