  SVN rev 190886 on 2009-04-10 10:16:03Z by kib
  
  When vm_map_wire(9) is allowed to skip holes in the wired region, skip
  the mappings without any of read and execution rights, in particular,
  the PROT_NONE entries. This makes mlockall(2) work for the process
  address space that has such mappings.
  
  Since protection mode of the entry may change between setting
  MAP_ENTRY_IN_TRANSITION and final pass over the region that records
  the wire status of the entries, allocate new map entry flag
  MAP_ENTRY_WIRE_SKIPPED to mark the skipped PROT_NONE entries.
