    kernel - Run AHCI and SILI disk drivers MPSAFE
    
    * These drivers now pass a port-disk-port lock in the cam sim registration,
      which should result in CAM callbacks being MPSAFE.
    
    * Add a separate signalling interlock for the port threads.
    
    * The devices were otherwise already MPSAFE, with per-port locking.
