Two changes to pmap_remove_all:

1. Switch to pmap_TLB_invalidate from invltlb, eliminating a full TLB
flush where a single-page flush suffices.  (Also, this eliminates some
unnecessary IPIs.)

2. Use "loadandclear" to update the pte, eliminating a race condition
on SMPs.

Change #2 should be committed to -STABLE.
