This was the (first and) last usage site outside of alternative.c, so at
the very least we should clean up arch/x86/include/asm/alternative.h.
However, since stop_machine now works early, is there any reason to keep
text_poke_early() itself? Shouldn't we also convert alternative.c's use
of text_poke_early and simply kill the thing off?
