  Log:
  MFC revisions 1.456, 1.458, and 1.464
   - Use VM_ALLOC_NOBUSY to eliminate vm_page_wakeup() calls and the
     acquisition and release of the global page queues lock required to make
     those calls.
   - Remove GIANT_REQUIRED from vm_hold_free_pages().  All of its VM operations
     are properly synchronized.
   - Hold the lock on the containing vm object when calling
     vm_page_sleep_if_busy().
   - Eliminate unnecessary calls to vm_page_busy().
