Re: [PATCH] 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, DMA address with all 64-bits set (0xFFFFFFFF-FFFFFFFF) results in a firmware fault.

Fix: Driver will set 63-bit DMA mask to ensure the above address will not be used.
