  Modified files:
    sys/vm               device_pager.c phys_pager.c swap_pager.c 
  Log:
  Protect pager object creation with sx locks.
  
  Protect pager object list manipulation with a mutex.
  
  It doesn't look possible to combine them under a single sx lock because
  creation may block and we can't have the object list manipulation block
  on anything other than a mutex because of interrupt requests.
