[0/4] iommu: Finish off PASID support for Arm SMMUv3

Message

Jean-Philippe Brucker Feb. 13, 2020, 10:14 a.m. UTC

Support for context descriptor tables was added to the SMMUv3 driver by
commit 87f42391f6a5 ("iommu/arm-smmu-v3: Add support for Substream
IDs"). The last patch enabling PASID in PCI devices couldn't be included
right away since it would have prevented from building SMMUv3 as a
module, another feature introduced in Linux v5.6. Export the relevant
symbols in patch 1 before using them in patch 2. Patches 3 and 4 address
the other remaining comments for the PASID series [1].
