this is a first stab at implementing SMR support. The powers that be decided to call the ATA implementation 'ZAC' (zoned access commands), and the SCSI implementation 'ZBC' (zoned block commands). This is just basic enablement to get ZAC and ZBC drives handled correctly. The first three patches update the libata SATL to handle ZAC devices correctly, and the last patch updates the 'sd' to work correctly with ZBC devices. ZBC devices will _not_ be handled with the 'sd' driver automatically ss of now; however, the sd device can be bound manually to the device by using the sysfs 'bind' attribute. None of the specific commands like 'report zones' or 'reset write pointer' have been implemented yet as the actual format is still not finalized. This patch is made against the core-for-3.17 tree from hch.
