Merge branch 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: - an update for clkdev registration error detection to simplify users - add cpu capacity parsing from DT - support for larger cachelines found on UniPhier caches - documentation for udelay constants - properly tag assembly function declarations - remove unnecessary indirection of asm/mach-types.h - switch to syscall table based generation to simplify future additions of system calls, along with correpsonding commit for pkey syscalls - remove redundant sa1101 header file - RONX protect modules when they're in the vmalloc region * 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: mm: allow set_memory_*() to be used on the vmalloc region ARM: mm: fix set_memory_*() bounds checks ARM: 8631/1: clkdev: Detect errors in clk_hw_register_clkdev() for mass registration ARM: 8629/1: vfp: properly tag assembly function declarations in C code ARM: 8622/3: add sysfs cpu_capacity attribute ARM: 8621/3: parse cpu capacity-dmips-mhz from DT ARM: 8623/1: mm: add ARM_L1_CACHE_SHIFT_7 for UniPhier outer cache ARM: Update mach-types ARM: sa1100: remove SA-1101 header file ARM: 8619/1: udelay: document the various constants ARM: wire up new pkey syscalls ARM: convert to generated system call tables ARM: remove indirection of asm/mach-types.h
