        src/sys/arch/amd64/amd64: locore.S

        src/sys/arch/x86/x86: cpu.c identcpu.c pmap.c

Log Message:
- Don't bother using sse to copy/zero pages on demand.  It turns out not
  to be worth it.
- If the machine has sse, re-enable zeroing pages in the idle loop and
  use the sse instructions so that we don't blow out the cache.
