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

Pull ARM fixes from Russell King:
 "Nothing too disasterous, the biggest thing being the removal of the
  regulator support for vcore in the AMBA driver; only one SoC was using
  this and it got broken during the last merge window, which then
  started causing problems for other people.  Mutual agreement was
  reached for it to be removed."

* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
  ARM: 7386/1: jump_label: fixup for rename to static_key
  ARM: 7384/1: ThumbEE: Disable userspace TEEHBR access for !CONFIG_ARM_THUMBEE
  ARM: 7382/1: mm: truncate memory banks to fit in 4GB space for classic MMU
  ARM: 7359/2: smp_twd: Only wait for reprogramming on active cpus
  ARM: 7383/1: nommu: populate vectors page from paging_init
  ARM: 7381/1: nommu: fix typo in mm/Kconfig
  ARM: 7380/1: DT: do not add a zero-sized memory property
  ARM: 7379/1: DT: fix atags_to_fdt() second call site
  ARM: 7366/3: amba: Remove AMBA level regulator support
  ARM: 7377/1: vic: re-read status register before dispatching each IRQ handler
  ARM: 7368/1: fault.c: correct how the tsk->[maj|min]_flt gets incremented
