Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King: "The biggest two fixes are fixing a compilation error with the decompressor, and a problem with our __my_cpu_offset implementation. Other changes are very trivial and small, which seems to be the way for most -rc stuff." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7747/1: pcpu: ensure __my_cpu_offset cannot be re-ordered across barrier() ARM: 7750/1: update legacy CPU ID in decompressor cache support jump table ARM: 7743/1: compressed/head.S: work around new binutils warning ARM: 7742/1: topology: export cpu_topology ARM: 7737/1: fix kernel decompressor compilation error with CONFIG_DEBUG_SEMIHOSTING
