Hi Linus, The following changes since commit afd2ff9b7e1b367172f18ba7f693dfb62bdcb2dc: Linux 4.4 (2016-01-10 15:01:32 -0800) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git tags/iommu-updates-v4.5 for you to fetch changes up to 32704253dc008dfedead71da016b00d10cd1854f: Merge branches 's390', 'arm/renesas', 'arm/msm', 'arm/shmobile', 'arm/smmu', 'x86/amd' and 'x86/vt-d' into next (2016-01-19 15:30:43 +0100) ---------------------------------------------------------------- IOMMU Updates for Linux v4.5 The updates include: * Small code cleanups in the AMD IOMMUv2 driver * Scalability improvements for the DMA-API implementation of the AMD IOMMU driver. This is just a starting point, but already showed some good improvements in my tests. * Removal of the unused Renesas IPMMU/IPMMUI driver * Updates for ARM-SMMU include: * Some fixes to get the driver working nicely on Broadcom hardware * A change to the io-pgtable API to indicate the unit in which to flush (all callers converted, with Ack from Laurent) * Use of devm_* for allocating/freeing the SMMUv3 buffers * Some other small fixes and improvements for other drivers ---------------------------------------------------------------- Dan Carpenter (1): iommu/amd: Remove an unneeded condition Geert Uytterhoeven (1): iommu/shmobile: Remove unused Renesas IPMMU/IPMMUI driver Joerg Roedel (28): iommu/amd: Correctly set flags for handle_mm_fault call iommu/amd: Cleanup error handling in do_fault() Merge branch 'for-joerg/arm-smmu/updates' of git://git.kernel.org/.../will/linux into arm/smmu iommu/amd: Warn only once on unexpected pte value iommu/amd: Move 'struct dma_ops_domain' definition to amd_iommu.c iommu/amd: Introduce bitmap_lock in struct aperture_range iommu/amd: Flush IOMMU TLB on __map_single error path iommu/amd: Flush the IOMMU TLB before the addresses are freed iommu/amd: Pass correct shift to iommu_area_alloc() iommu/amd: Add dma_ops_aperture_alloc() function iommu/amd: Move aperture_range.offset to another cache-line iommu/amd: Retry address allocation within one aperture iommu/amd: Flush iommu tlb in dma_ops_aperture_alloc() iommu/amd: Remove 'start' parameter from dma_ops_area_alloc iommu/amd: Rename dma_ops_domain->next_address to next_index iommu/amd: Flush iommu tlb in dma_ops_free_addresses iommu/amd: Iterate over all aperture ranges in dma_ops_area_alloc iommu/amd: Remove need_flush from struct dma_ops_domain iommu/amd: Optimize dma_ops_free_addresses iommu/amd: Allocate new aperture ranges in dma_ops_alloc_addresses iommu/amd: Build io page-tables with cmpxchg64 iommu/amd: Initialize new aperture range before making it visible iommu/amd: Relax locking in dma_ops path iommu/amd: Make dma_ops_domain->next_index percpu iommu/amd: Use trylock to aquire bitmap_lock iommu/amd: Preallocate dma_ops apertures based on dma_mask iommu/vt-d: Fix up error handling in alloc_iommu Merge branches 's390', 'arm/renesas', 'arm/msm', 'arm/shmobile', 'arm/smmu', 'x86/amd' and 'x86/vt-d' into next Julia Lawall (1): iommu/amd: Constify mmu_notifier_ops structures Magnus Damm (1): iommu/ipmmu-vmsa: Include SoC part number in DT binding docs Markus Elfring (1): iommu/arm-smmu: Delete an unnecessary check before free_io_pgtable_ops() Nicholas Krause (1): iommu/vt-d: Check the return value of iommu_device_create() Peng Fan (1): iommu/arm-smmu: Correct group reference count Prem Mallappa (2): iommu/arm-smmu: Fix write to GERRORN register iommu/arm-smmu: Use STE.S1STALLD only when supported Robin Murphy (4): iommu/io-pgtable-arm: Avoid dereferencing bogus PTEs iommu/io-pgtable: Indicate granule for TLB maintenance iommu/arm-smmu: Invalidate TLBs properly iommu/io-pgtable: Make io_pgtable_ops_to_pgtable() macro common Sebastian Ott (1): iommu/s390: Fix sparse warnings Thierry Reding (1): iommu/msm: Use platform_register/unregister_drivers() Will Deacon (5): iommu/arm-smmu: Remove #define for non-existent PRIQ_0_OF field iommu/arm-smmu: Convert DMA buffer allocations to the managed API iommu/arm-smmu: Use incoming shareability attributes in bypass mode iommu/arm-smmu: Handle unknown CERROR values gracefully iommu/io-pgtable-arm: Ensure we free the final level on teardown .../bindings/iommu/renesas,ipmmu-vmsa.txt | 12 +- drivers/iommu/Kconfig | 75 ---- drivers/iommu/Makefile | 2 - drivers/iommu/amd_iommu.c | 396 ++++++++++++-------- drivers/iommu/amd_iommu_types.h | 40 -- drivers/iommu/amd_iommu_v2.c | 38 +- drivers/iommu/arm-smmu-v3.c | 210 ++++------- drivers/iommu/arm-smmu.c | 23 +- drivers/iommu/dmar.c | 12 +- drivers/iommu/io-pgtable-arm.c | 49 +-- drivers/iommu/io-pgtable.h | 6 +- drivers/iommu/ipmmu-vmsa.c | 4 +- drivers/iommu/msm_iommu_dev.c | 25 +- drivers/iommu/s390-iommu.c | 4 +- drivers/iommu/shmobile-iommu.c | 402 --------------------- drivers/iommu/shmobile-ipmmu.c | 129 ------- drivers/iommu/shmobile-ipmmu.h | 34 -- 17 files changed, 411 insertions(+), 1050 deletions(-) delete mode 100644 drivers/iommu/shmobile-iommu.c delete mode 100644 drivers/iommu/shmobile-ipmmu.c delete mode 100644 drivers/iommu/shmobile-ipmmu.h Please pull.
