* Add ->set_capacity block device method and use it in rescan_partitions() to attempt enabling native capacity of the device upon detecting the partition which exceeds device capacity. * Add GENHD_FL_NATIVE_CAPACITY flag to try limit attempts of enabling native capacity during partition scan. Together with the consecutive patch implementing ->set_capacity method in ide-gd device driver this allows automatic disabling of Host Protected Area (HPA) if any partitions overlapping HPA are detected.
