iommu/amd: Fix PASID format in INVALIDATE_IOTLB_PAGES command
commit e8d2d82d4a73f37b3270e4fd19ba83e48b589656 upstream.
This patch corrects the PASID format in the INVALIDATE_IOTLB_PAGES
command, which was caused by incorrect information in
the AMD IOMMU Architectural Specification v2.01 document.
Incorrect format:
cmd->data[0][16:23] = PASID[7:0]
cmd->data[1][16:27] = PASID[19:8]
Correct format:
cmd->data[0][16:23] = PASID[15:8]
cmd->data[1][16:23] = PASID[7:0]
However, this does not affect the IOMMUv2 hardware implementation,
and has been corrected since version 2.02 of the specification
(available through AMD NDA).
