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
