Re: [PATCH] mpt2sas: Fall back to 64 bit coherent mask if 64 bit DMA / 32 bit coherent mask not supported

Hi Brain, We had a restriction from the firmware that the upper 32 bits of the RDPQ pool entries must be same. So to limit this restriction we initially set the consistent DMA mask to 32 and then after allocating the RDPQ pools we changed the consistent DMA mask to 64 before allocating remaining p
