Pull ARM updates from Russell King: - Major clean-up of the L2 cache support code. The existing mess was becoming rather unmaintainable through all the additions that others have done over time. This turns it into a much nicer structure, and implements a few performance improvements as well. - Clean up some of the CP15 control register tweaks for alignment support, moving some code and data into alignment.c - DMA properties for ARM, from Santosh and reviewed by DT people. This adds DT properties to specify bus translations we can't discover automatically, and to indicate whether devices are coherent. - Hibernation support for ARM - Make ftrace work with read-only text in modules - add suspend support for PJ4B CPUs - rework interrupt masking for undefined instruction handling, which allows us to enable interrupts earlier in the handling of these exceptions. - support for big endian page tables - fix stacktrace support to exclude stacktrace functions from the trace, and add save_stack_trace_regs() implementation so that kprobes can record stack traces. - Add support for the Cortex-A17 CPU. - Remove last vestiges of ARM710 support. - Removal of ARM "meminfo" structure, finally converting us solely to memblock to handle the early memory initialisation. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (142 commits) ARM: ensure C page table setup code follows assembly code (part II) ARM: ensure C page table setup code follows assembly code ARM: consolidate last remaining open-coded alignment trap enable ARM: remove global cr_no_alignment ARM: remove CPU_CP15 conditional from alignment.c ARM: remove unused adjust_cr() function ARM: move "noalign" command line option to alignment.c ARM: provide common method to clear bits in CPU control register ARM: 8025/1: Get rid of meminfo ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory type ARM: 8066/1: correction for ARM patch 8031/2 ARM: 8049/1: ftrace/add save_stack_trace_regs() implementation ARM: 8065/1: remove last use of CONFIG_CPU_ARM710 ARM: 8062/1: Modify ldrt fixup handler to re-execute the userspace instruction ARM: 8047/1: rwsem: use asm-generic rwsem implementation ARM: l2c: trial at enabling some Cortex-A9 optimisations ARM: l2c: add warnings for stuff modifying aux_ctrl register values ARM: l2c: print a warning with L2C-310 caches if the cache size is modified ARM: l2c: remove old .set_debug method ARM: l2c: kill L2X0_AUX_CTRL_MASK before anyone else makes use of this ...

2014-03-21ARM: msm: avoid calling debug_ll_addr on !MMUArnd Bergmann
MSM7X00A has an open-coded version of debug_ll_io_init so it can use MT_DEVICE_NONSHARED as required by the platform. However, this fails to build on no-MMU kernels because the debug_ll_addr function is not available. Since the iotable_init function doesn't actually do anyting in this configuration, we can simply get away by enclosing the broken function call in an #ifdef, which seems to be the least ugly workaround.

next/cleanup This cleanup series gets rid of <mach/timex.h> for platforms not using ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since 387798b (ARM: initial multiplatform support).) To make this work some code out of arch/arm needed to be adapted. The respective changes got acks by their maintainers to be taken via armsoc (with Andrew Morton substituting for Alessandro Zummo as rtc maintainer). Compared to the previous pull request there was another patch added that fixes a (non-critical) regression on ixp4xx.

2014-01-09ARM: msm: Move MSM's DT based hardware to multi-platform supportStephen Boyd
The DT based MSM platforms can join the multi-platform builds, so introduce a DT based ARCH_MSM option. This option allows DT based MSM platforms to be built into the multi-platform kernel. Also introduce a hidden ARCH_MSM config that both the DT and non-DT platform support code select to avoid churn in places that depend on CONFIG_ARCH_MSM.

In downstream kernel we've standardized the clock consumer names that MSM device drivers use. Replace the uart specific clock names in this driver with the more standard 'core' and 'iface' names. Also simplify the code by assuming that clk_prepare_enable and clk_disable_unprepare() will properly check for NULL pointers (it will because MSM uses the common clock framework).

Only the non-dt based MSM platforms need to map memory from their machine descriptor. Unfortunately it is always compiled if ARCH_MSM=y and the file also has mach/ includes in it. Since dt-based MSM platforms aren't actually using anything in this file just compile io.c on the non-dt based MSM platforms.
