The most important one is probably, that dma-debug now warns if a dma-handle is not checked with dma_mapping_error by the device driver. This requires minor changes to some architectures which make use of dma-debug. Most of these changes have the respective Acks by the Arch-Maintainers. Besides that there are updates to the AMD IOMMU driver for refactor the IOMMU-Groups support and to make sure it does not trigger a hardware erratum. The OMAP changes (for which I pulled in a branch from Tony Lindgren's tree) have a conflict in linux-next with the arm-soc tree. The conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in the arm-soc tree. It is safe to delete the file too so solve the conflict. Similar changes are done in the arm-soc tree in the common clock framework migration. A missing hunk from the patch in the IOMMU tree will be submitted as a seperate patch when the merge-window is closed." * tag 'iommu-updates-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (29 commits) ARM: dma-mapping: support debug_dma_mapping_error ARM: OMAP4: hwmod data: ipu and dsp to use parent clocks instead of leaf clocks iommu/omap: Adapt to runtime pm iommu/omap: Migrate to hwmod framework iommu/omap: Keep mmu enabled when requested iommu/omap: Remove redundant clock handling on ISR iommu/amd: Remove obsolete comment iommu/amd: Don't use 512GB pages iommu/tegra: smmu: Move bus_set_iommu after probe for multi arch iommu/tegra: gart: Move bus_set_iommu after probe for multi arch iommu/tegra: smmu: Remove unnecessary PTC/TLB flush all tile: dma_debug: add debug_dma_mapping_error support sh: dma_debug: add debug_dma_mapping_error support powerpc: dma_debug: add debug_dma_mapping_error support mips: dma_debug: add debug_dma_mapping_error support microblaze: dma-mapping: support debug_dma_mapping_error ia64: dma_debug: add debug_dma_mapping_error support c6x: dma_debug: add debug_dma_mapping_error support ARM64: dma_debug: add debug_dma_mapping_error support intel-iommu: Prevent devices with RMRRs from being placed into SI Domain ...

The FMN queues and credits needs to be configured and intialized before it can be used. The co-processor 2 on XLR/XLS CPU cores has registers for FMN access, and the XLR/XLS has custom instructions for sending and loading messages. The FMN can deliver also per-cpu interrupts when messages are available at the CPU. This patch adds FMN initialization, adds interrupt setup and handling, and also provides support for sending and receiving FMN messages.

In addition some values like boardtype are stored without a prefix for the main SoC chip also when they have an additional PCIe wifi chip with an own boardtype var on some devices. The Ethernet addresses are now also read out correctly without a prefix so calling bcm47xx_fill_sprom_ethernet is not needed any more.

This should fix a problem we saw in OpenWrt, where the detected available memory decreed on some devices when doing a soft reboot.

Unfortunately, after this commit, the coherency kernel parameters, cca and coherentio, are no longer processed before their values are used. This patch fixes this problem by marking them as early_param, which results in them being processed before they are needed.

The simple solution was to add the code that queries the configuration register for the width of the bus that has been hardware strapped to the Cavium. This allows both 8-bit and 16-bit parts to be discovered during boot.
