  SVN rev 213890 on 2010-10-15 05:42:35Z by alc
  
  MFC r209605
    Improve bufdone_finish()'s handling of the bogus page.  Specifically, if
    one or more mappings to the bogus page must be replaced, call pmap_qenter()
    just once.  Previously, pmap_qenter() was called for each mapping to the
    bogus page.
  
  MFC r209902
    Change the implementation of vm_hold_free_pages() so that it performs at
    most one call to pmap_qremove(), and thus one TLB shootdown, instead of one
    call and TLB shootdown per page.
  
    Simplify the interface to vm_hold_free_pages().
