  Log:
  Add comments explaining why all stores updating a non-kernel page table
  must be globally performed before calling any of the TLB invalidation
  functions.
  
  With one exception, on amd64, this requirement was already met.  Fix this
  one case.  Also, as a clarification, change an existing atomic op into a
  release.  (Suggested by: jhb)
