Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm

Pull ARM fixes from Russell King:
 "The larger changes this time are

   - "ARM: 7755/1: handle user space mapped pages in flush_kernel_dcache_page"
     which fixes more data corruption problems with O_DIRECT

   - "ARM: 7759/1: decouple CPU offlining from reboot/shutdown" which
     gets us back to working shutdown/reboot on SMP platforms

   - "ARM: 7752/1: errata: LoUIS bit field in CLIDR register is incorrect"
     which fixes a shutdown regression found in v3.10 on Versatile
     Express platforms.

  The remainder are the quite small, maybe one or two line changes"
