Damien Le Moal bd9c447cda scsi: mpi3mr: Avoid IOMMU page faults on REPORT ZONES 
commit 1abc900ddd upstream.

Some firmware versions of the 9600 series SAS HBA byte-swap the REPORT
ZONES command reply buffer from ATA-ZAC devices by directly accessing the
buffer in the host memory. This does not respect the default command DMA
direction and causes IOMMU page faults on architectures with an IOMMU
enforcing write-only mappings for DMA_FROM_DEVICE DMA direction (e.g. AMD
hosts), leading to the device capacity to be dropped to 0:

scsi 18:0:58:0: Direct-Access-ZBC ATA      WDC  WSH722626AL W930 PQ: 0 ANSI: 7

sd 18:0:58:0: [sdj] Write cache: enabled, read cache: enabled, supports DPO and FUA
sd 18:0:58:0: [sdj] Attached SCSI disk

Avoid this issue by always mapping the buffer of REPORT ZONES commands
using DMA_BIDIRECTIONAL, that is, using a read-write IOMMU mapping.
