Cover letter [PATCH 0/8] io-pgtable lock removal
Hi all,
Here's the cleaned up nominally-final version of the patches everybody's keen to see. #1 is just a non-critical thing-I-spotted-in-passing fix, #2-#4 do some preparatory work (and bid farewell to everyone's least favourite bit of code, hooray!), and #5-#8 do the dirty deed itself.
The branch I've previously shared has been updated too:
git://linux-arm.org/linux-rm iommu/pgtable
All feedback welcome, as I'd really like to land this for 4.13.
Robin.
