Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King: "Another couple of small ARM fixes. A patch from Masahiro Yamada who noticed that "make -jN all zImage" would end up generating bad images where N > 1, and a patch from Nicolas to fix the Marvell CPU user access optimisation code when page faults are disabled" * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: ARM: 8418/1: add boot image dependencies to not generate invalid images ARM: 8414/1: __copy_to_user_memcpy: fix mmap semaphore usage
