  SVN rev 215819 on 2010-11-25 15:41:34Z by cperciva
  
  Work around paging bug.  Somehow we seem to be ending up with entries in
  the TLB which don't correspond to ptes with PG_V set; prior to this commit
  I'm sometimes getting the wrong data when pages are loaded into the buffer
  cache (they're being loaded, but the missing TLB invalidation is causing
  the wrong data to be visible).
