Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into next
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 ...
