Pull ARM updates from Russell King:
"First ARM push of this merge window, post me coming back from holiday.
This is what has been in linux-next for the last few weeks. Not much
to say which isn't described by the commit summaries."
* 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (32 commits)
ARM: 7463/1: topology: Update cpu_power according to DT information
ARM: 7462/1: topology: factorize the update of sibling masks
ARM: 7461/1: topology: Add arch_scale_freq_power function
ARM: 7456/1: ptrace: provide separate functions for tracing syscall {entry,exit}
ARM: 7455/1: audit: move syscall auditing until after ptrace SIGTRAP handling
ARM: 7454/1: entry: don't bother with syscall tracing on ret_from_fork path
ARM: 7453/1: audit: only allow syscall auditing for pure EABI userspace
ARM: 7452/1: delay: allow timer-based delay implementation to be selected
ARM: 7451/1: arch timer: implement read_current_timer and get_cycles

ARM: 7448/1: perf: remove arm_perf_pmu_ids global enumeration
ARM: 7447/1: rwlocks: remove unused branch labels from trylock routines
ARM: 7446/1: spinlock: use ticket algorithm for ARMv6+ locking implementation
ARM: 7445/1: mm: update CONTEXTIDR register to contain PID of current process
ARM: 7444/1: kernel: add arch-timer C3STOP feature
ARM: 7460/1: remove asm/locks.h
ARM: 7439/1: head.S: simplify initial page table mapping
ARM: 7437/1: zImage: Allow DTB command line concatenation with ATAG_CMDLINE
