   Continue the transition from synchronizing access to the page's PG_BUSY
   flag and busy field with the global page queues lock to synchronizing
   their access with the containing object's lock.  Specifically, acquire the
   containing object's lock before reading the page's PG_BUSY flag and busy
   field in vm_fault().
