    kernel - Add KVABIO support to NVMe, disk translation layer, and swap
    
    * Add KVABIO support to the NVMe driver.  The driver no longer
      requires that buffers be synchronized to all cpus.
    
    * Add KVABIO support to the disk translation layer.  The layer no
      longer requires that buffers besynchronized to all cpus (note
      however that the underlying device may still require such).
    
    * Add KVABIO support to the swap subsystem.  Again, actual avoidance
      of buffer memory synchronization depends on the underlying devices.
