Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King: "A set of fixes from various people - Will Deacon gets a prize for removing code this time around. The biggest fix in this lot is sorting out the ARM740T mess. The rest are relatively small fixes." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7699/1: sched_clock: Add more notrace to prevent recursion ARM: 7698/1: perf: fix group validation when using enable_on_exec ARM: 7697/1: hw_breakpoint: do not use __cpuinitdata for dbg_cpu_pm_nb ARM: 7696/1: Fix kexec by setting outer_cache.inv_all for Feroceon ARM: 7694/1: ARM, TCM: initialize TCM in paging_init(), instead of setup_arch() ARM: 7692/1: iop3xx: move IOP3XX_PERIPHERAL_VIRT_BASE ARM: modules: don't export cpu_set_pte_ext when !MMU ARM: mm: remove broken condition check for v4 flushing ARM: mm: fix numerous hideous errors in proc-arm740.S ARM: cache: remove ARMv3 support code ARM: tlbflush: remove ARMv3 support
