Description

Andy Giles made a few changes to how auto request sense works in mpt_sas. Request sense buffers will be preallocated as one big buffer to make it possible to use 64bit DMA (hardware limitation, only one register for high 32bits of the 64bit address). Also, the last sense data will be recorded in DEBUG builds.
