Subject: [GIT PULL] iommu/arm-smmu: Updates for 4.15
Message-ID: <20171020161154.GA7287@arm.com>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

Hi Joerg,

Please pull these ARM SMMU updates for 4.15. The main improvement here is
that we now drop the command queue lock when waiting for a CMD_SYNC to
complete on implementations that support MSIs into cacheable memory.
There are also some minor fixes and cleanups.

Cheers,

Will
