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
