    kernel - Adjust device D_MPSAFE_* flags
    
    * Replace all device D_MPSAFE_* flags with just D_MPSAFE
        - Mark CAM's "da" and "cd" devices D_MPSAFE
        - Mark dm (device mapper) D_MPSAFE
        - Mark memio MPSAFE
        - Mark the disk subsystem D_MPSAFE
        - Mark the crypto device D_MPSAFE
    
    * Devices marked D_MPSAFE now call their strategy functions without the
      mp lock.
    
    * Do a pass on devfs and mark it MNTK_ALL_MPSAFE.  devfs was essentially
      already MPSAFE but the D_MPSAFE checks have been moved out of devfs
      and into the dev_d*() API wrappers.
