    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.
