      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)
