    Linus Torvalds authored
    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.
