[Intel-gfx] [core-for-CI][PATCH v2 0/2] iommu: Remove iova cpu hotplugging flushing

[Janusz Krzysztofik]

Manual revert of commit f598a497bc7d ("iova: Add CPU hotplug handler to
flush rcaches").  It is trying to instantiate a cpuhp notifier from inside
a cpuhp callback.  That code replaced intel_iommu implementation of
flushing per-IOVA domain CPU rcaches which used a single instance of cpuhp
held for the module lifetime.

v2: Restore formerly reverted commit ac9a5d522bb8 "iommu/dma: Fix race
    condition during iova_domain initialization" after we have this more
    effective fix applied.  The former occurred not sufficient and is no
    longer needed once we have the latter in place.

Note: I'm no longer CCing IOMMU nor mainstream, they have been already
      warned.
