Suganath Prabu df9a606184 scsi: mpt3sas: Use 63-bit DMA addressing on SAS35 HBA ... Although SAS3 & SAS3.5 IT HBA controllers support 64-bit DMA addressing, as per hardware design, if DMA-able range contains all 64-bits set (0xFFFFFFFF-FFFFFFFF) then it results in a firmware fault. E.g. SGE's start address is 0xFFFFFFFF-FFFF000 and data length is 0x1000 bytes. when HBA tries to DMA the data at 0xFFFFFFFF-FFFFFFFF location then HBA will fault the firmware. Driver will set 63-bit DMA mask to ensure the above address will not be used.
