[PATCH v2 0/4] IOMMU reserved region tweaks

[Robin Murphy <robin.murphy-5wv7dgnIgG8@public.gmane.org>]

Hi Joerg,

Here's v2 incorporating Eric's feedback and R-b tags, with patch #4 added
to finish the job. Whilst presented as a logical series because it's all
touching the same code, it doesn't necessarily need merging as such - I'd
be happier with patch #1 going into 4.11 before anyone starts using the
sysfs region info in anger, but it's your call; #2 is really a standalone
fix (other than context conflicts) but is non-urgent; #3 and #4 can
happily wait for 4.12.

Robin.

Robin Murphy (4):
  iommu: Disambiguate MSI region types
  iommu/dma: Don't reserve PCI I/O windows
  iommu/dma: Handle IOMMU API reserved regions
  iommu/dma: Make PCI window reservation generic
