Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King: "This is mainly audit fixes, found by folks who happened to enable this feature and then found it broke their user applications." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7414/1: SMP: prevent use of the console when using idmap_pgd ARM: 7412/1: audit: use only AUDIT_ARCH_ARM regardless of endianness ARM: 7411/1: audit: fix treatment of saved ip register during syscall tracing ARM: 7410/1: Add extra clobber registers for assembly in kernel_execve
