Ok, looks real good, the simplification is amazing! :)
Can you please redo with the minor nits addressed ontop of the
tip:x86/alternatives branch:
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/log/?h=x86/alternatives
and move the cleanups patches 13 and 14 to the beginning of the set?
Thx.
