[PATCH v2 0/2] Simplify and restrict IOMMU SVA APIs

[Jacob Pan]

A couple of small changes to simplify and restrict SVA APIs. The motivation
is to make PASID allocation palatable for cgroup consumptions. Misc cgroup
is merged for v5.13, it can be extended for IOASID as another scalar
resource.

I have not tested on ARM platforms due to availability. Would appreciate
if someone could help with the testing on ARM.

Thanks,

Jacob

ChangeLog:
V2
	- retained mm argument in iommu_sva_alloc_pasid()
	- keep generic supervisor flag separated from vt-d's SRE
	- move flag declaration out of CONFIG_IOMMU_API


Jacob Pan (2):
  iommu/sva: Tighten SVA bind API with explicit flags
  iommu/sva: Remove mm parameter from SVA bind API
