From mboxrd@z Thu Jan 1 00:00:00 1970 From: robin.murphy@arm.com (Robin Murphy) Date: Wed, 13 Apr 2016 18:12:56 +0100 Subject: [PATCH 0/7] arm-smmu: Implementation and context format differentiation Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hi all, This is almost 3 separate sub-series, but there's enough interdependency and horrid merge conflicts that I've been keeping it all together. - Patches 1-3 rationalise implementation-specific details and errata, in order to start shovelling in yet more wonderful workarounds. - Patches 3-6 do a broadly similar thing for context formats, breaking the effective hard-coding to allow it to become a runtime choice. (With the bonus of unblocking short-descriptor support, once I find and revive the hac^Wpatches I was using for that.) - Patch 7 then takes advantage of the previous changes to support the hilarious raison d'etre of MMU-401, in all its glory. This is all based on top of the ThunderX patches in Will's iommu/devel branch. It also conflicts somewhat with my per-domain page size series; since this is probably less contentious, I expect I'll optimistically rebase that on top of this one before I post it again.
