* ARM: delete struct sys_timerStephen Warren2012-12-242-18/+1
| | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

* ARM: remove struct sys_timer suspend and resume fieldsStephen Warren2012-12-241-11/+0
| | | | | | | | | | | These fields duplicate e.g. struct clock_event_device's suspend and resume fields, so remove them now that nothing is using them. The aim is to remove all fields from struct sys_timer except .init, then replace the ARM machine descriptor's .timer field with a .init_time function instead, and delete struct sys_timer.

* ARM: set arch_gettimeoffset directlyStephen Warren2012-12-241-3/+0
| | | | | | | | | | | | | | | | | | | remove ARM's struct sys_timer .offset function pointer, and instead directly set the arch_gettimeoffset function pointer when the timer driver is initialized. This requires multiplying all function results by 1000, since the removed arm_gettimeoffset() did this. Also, s/unsigned long/u32/ just to make the function prototypes exactly match that of arch_gettimeoffset.

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 ...

Different board design may choose different port as debug uart. For example, imx6q-sabresd uses UART1, imx6q-sabrelite uses UART2 and imx6q-arm2 uses UART4. Rather than bloating DEBUG_LL choice list with all these uart ports, the patch introduces DEBUG_IMX6Q_UART_PORT for users to input uart port number when DEBUG_IMX6Q_UART is selected inside DEBUG_LL choice.

The new Broadcom platform is contributed by Christian Daudt. Highbank has grown support for Calxeda's next generation of hardware, ECX-2000. clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also taken on maintainership of the platform. Beyond this there has been a bunch of work from a number of people on converting more platforms to IRQ domains, pinctrl conversion, cleanup and general feature enablement across most of the active platforms."

Later, when the page tables are replaced, the same virtual address must remain valid. Historically, this has been ensured by using defines from <mach/iomap.h> in both the implementation of addruart, and the machine's .map_io() function. However, with the move to single zImage, we wish to remove <mach/iomap.h>. To enable this, the macro addruart may be used when constructing the late page tables too; addruart is exposed as a C function debug_ll_addr(), and used to set up the required mapping in debug_ll_io_init(), which may called on an opt-in basis from a machine's .map_io() function.

There's a bunch of patch series from Will tackling various bugs like the PROT_NONE handling, ASID allocation, cluster boot protocol and ASID TLB tagging updates. We move to a build-time sorted exception table rather than doing the sorting at run-time, add support for the secure computing filter, and some updates to the perf code. We also have sorted out the placement of some headers, fixed some build warnings, fixed some hotplug problems with the per-cpu TWD code." * 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (73 commits) ARM: 7594/1: Add .smp entry for REALVIEW_EB ARM: 7599/1: head: Remove boot-time HYP mode check for v5 and below ARM: 7598/1: net: bpf_jit_32: fix sp-relative load/stores offsets.
