Many ASM code in entry_64.S can be rewritten in C if they can be written
to be non-instrumentable and are called in the right order regarding to
whether CR3/gsbase is changed to kernel CR3/gsbase.

The patchset covert some of them to C code.

Overall, very nice! There's a lot of details to verify, but I really
like where this ends up.

I'm not sure about moving traps.c, but whatever, that's simple stuff.
I'll try and put some more eyeballs on this later.
