Peter, please consider this (hopefully simple) change for inclusion.
Denys, Andy, could you review?
I guess (I hope ;) Denys is going to resend his entry.S/etc rework, but
this change should not conflict with his work, just preempt.S goes away.
Oleg.

___preempt_schedule() does SAVE_ALL/RESTORE_ALL but this is suboptimal,
we do not need to save/restore the callee-saved register. And we already
have arch/x86/lib/thunk_*.S which implements the similar asm wrappers,
so it makes sense to redefine ___preempt_schedule() as "THUNK ..." and
remove preempt.S altogether.

Trivial. We have "lib-y += thunk_$(BITS).o" at the start, no need
to add thunk_64.o if !CONFIG_X86_32.

I think THUNK should be thunk_ra here;
or thunk_ra should be renamed to THUNK (like it is in thunk_64.S)
