[PATCH 0/3] Misc IOVA tweaks

[Robin Murphy]

While I was elbow-deep in the IOVA code, a few other things came to
light which don't really fit into the rbtree optimisation series.
Patches #1 and #2 are more or less just cleanup, while patch #3
complements Tomasz' recent PCI allocation patch as it aims to
potentially improve the same situation.

Last time I checked, these should all apply independently and without
major conflicts against any other in-flight IOVA patches.

Robin.

Robin Murphy (3):
  iommu/iova: Simplify domain destruction
  iommu/iova: Make rcache limit_pfn handling more robust
  iommu/iova: Try harder to allocate from rcache magazine
