Modified Files:
	syssrc/sys/arch/alpha/alpha: pmap.c

Log Message:
More MP cleanup:
- Make sure to do an MB after a PTE is set to a new value, so that
  other processors see it.
- Use lazy I-sync in two pmap_page_protect() and in pmap_changebit(),
  so that it is MP-safe.  XXX Two more places where IMB is used in
  the raw, but they're not in the common path.

There'll be some more lazy I-sync cleanups soon.
