Hi all,

Hopefully this is the last spin of the series - I've now dropped my light
touch and fixed up all the various prose text, plus implemented the 
proper
quirk support for short-descriptor because it's actually just a trivial
cut-and-paste job.

Hi Robin,

JFYI, I'm trying to test this patchset to get some figures and provide a 
tested-by tag, but 4/8 seems to rely on "iommu/io-pgtable-arm: Fix race 
handling in split_blk_unmap()" - more specifically, it seems to rely on 
the version which Will rewrote in your patch review, and I am not sure 
on what branch it exists on, if any.

Sorry, I should have said this is based on Will's iommu/devel branch:

https://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git/log/?h=iommu/devel

Robin.

Thanks,
John
