The highlights are: * Support for 64k pages with SMMUv1 implementations (e.g MMU-401) * Remove open-coded 64-bit MMIO accessors * Initial support for 16-bit VMIDs, as supported by some ThunderX SMMU implementations * A couple of errata workarounds for silicon in the field As a result of the MMIO accessor rework, there is an asm-generic change here, but it has been Acked-by Arnd. Thanks, Will --->8 The following changes since commit f55532a0c0b8bb6148f4e07853b876ef73bc69ca: Linux 4.6-rc1 (2016-03-26 16:03:24 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git for-joerg/arm-smmu/updates for you to fetch changes up to 3ca3712a42f9e632eb41da94ca4eab4f1fb06fcb: iommu/arm-smmu: Clear cache lock bit of ACR (2016-05-03 18:23:04 +0100) ---------------------------------------------------------------- Peng Fan (1): iommu/arm-smmu: Clear cache lock bit of ACR Robin Murphy (7): iommu/arm-smmu: Differentiate specific implementations iommu/arm-smmu: Convert ThunderX workaround to new method iommu/arm-smmu: Work around MMU-500 prefetch errata io-64-nonatomic: Add relaxed accessor variants iommu/arm-smmu: Tidy up 64-bit/atomic I/O accesses iommu/arm-smmu: Decouple context format from kernel config iommu/arm-smmu: Support SMMUv1 64KB supplement Tirumalesh Chalamarla (2): iommu/arm-smmu: Add support for 16 bit VMID iommu/arm-smmu: Workaround for ThunderX erratum #27704 Documentation/arm64/silicon-errata.txt | 2 + .../devicetree/bindings/iommu/arm,smmu.txt | 1 + drivers/iommu/arm-smmu.c | 291 +++++++++++++++------ include/asm-generic/io.h | 4 +- include/linux/io-64-nonatomic-hi-lo.h | 25 ++ include/linux/io-64-nonatomic-lo-hi.h | 25 ++ 6 files changed, 265 insertions(+), 83 deletions(-)
