This patch adds a framework for hot-swapping drives on libata-run
controllers. The functions 'sata_hot_plug' and 'sata_hot_unplug' can
be called by low level hotswap-capable SATA controllers, and
subsequent functions in the call chain will (in the future) be entry
points for PATA warm-swapping of drives.
