  Log:
  Changes to msync(2)
   - Return EBUSY if the region was wired by mlock(2) and MS_INVALIDATE
     is specified to msync(2).  This is required by the Open Group Base
     Specifications Issue 6.
   - vm_map_sync() doesn't return KERN_FAILURE.  Thus, msync(2) can't
     possibly return EIO.
   - The second major loop in vm_map_sync() handles sub maps.  Thus,
     failing on sub maps in the first major loop isn't necessary.
