Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
"Just two ARM fixes this time: one to fix the hyp-stub for older ARM
CPUs, and another to fix the set_memory_xx() permission functions to
deal with zero sizes correctly"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8544/1: set_memory_xx fixes
ARM: 8534/1: virt: fix hyp-stub build for pre-ARMv7 CPUs
