  Log:
  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().
