Pull ARM fixes from Russell King: "A number of low impact fixes, the most noticable one is the thumb2 frame pointer fix. We also fix a regression caused during this merge window with ARM925 CPUs running with caches disabled, and fix a number of warnings" * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: ARM: arm925: ensure assembly sets up writethrough mapping ARM: perf: fix compiler warning with gcc 4.6.4 (and tidy code) ARM: l2c: fix dependencies on PL310 errata symbols ARM: 8069/1: Make thread_save_fp macro aware of THUMB2 mode ARM: 8068/1: scoop: Remove unused variable
2014-06-19ARM: l2c: fix dependencies on PL310 errata symbolsRussell King
A number of configurations spit out warnings similar to: warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0) warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0) Clean up the dependencies here: * PL310 symbols should only be selected when CACHE_L2X0 is enabled. * Since the cache-l2x0 code detects PL310 presence at runtime, and we will eventually get rid of CACHE_PL310, surround these errata options with an if CACHE_L2X0 conditional rather than repeating the dependency against each.

2014-06-17ARM: use menuconfig for sub-arch menusRob Herring
The System Type menu is getting quite long with platforms and is inconsistent in handling of sub-arch specific options. Tidy up the menu by making platform options a menuconfig entry containing any platform specific config items.

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 ...

2013-08-04ARM: STi: remove sti_secondary_start from INIT section.Srinivas Kandagatla
This patch removes sti_secondary_start from _INIT section, there are 2 reason for this removal. 1. discarding such a small code does not save much, given the RAM sizes. 2. Having this code discarded, creates corruption issue when we boot smp-kernel with nrcpus=1 or with single cpu node in DT.

2013-07-14arm: delete __cpuinit/__CPUINIT usage from all ARM usersPaul Gortmaker
The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.
