The page fault handling framework within the iommu core has defined the
PRI enable and disable flows in the comments for the
iopf_queue_remove_device() interface. This series aims to refactor the
PRI enable/disable steps in the Intel iommu driver to align with these
definitions.

Change log:

v2:
- The cache invalidation for a context entry change should not affect
the devices not related to the entry. Fix this by always using
device-selective cache invalidation.
v1:
- https://lore.kernel.org/linux-iommu/20240606034019.42795-1-baolu.lu@linux.intel.com/

Lu Baolu (2):
iommu/vt-d: Add helper to flush caches for context change
iommu/vt-d: Refactor PCI PRI enabling/disabling callbacks
