Subject[PATCH 0/3] iommu/iova: Add CPU hotplug handler to flush rcaches to core code
Date
The Intel IOMMU driver supports flushing the per-CPU rcaches when a CPU is
offlined.

Let's move it to core code, so everyone can take advantage.

Also correct a code comment.

Based on v5.12-rc1. Tested on arm64 only.
