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
