[PATCH v2] mpt3sas: Use 63-bit DMA addressing on SAS35 HBA

2019-07-30 Thread Suganath Prabu
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 (0x-) then it results in a firmware fault. e.g. SGE's start address is 0x-000 and data length is 0x1000 bytes. when HBA tries to D
