Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
"A small set of ARM fixes for -rc3, most of them not far off
one-liners, with the exception of fixing the V7 cache invalidation for
incoming SMP processors which was causing problems for SoCFPGA
devices"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: fix __virt_to_idmap build error on !MMU
ARM: invalidate L1 before enabling coherency
ARM: 8404/1: dma-mapping: fix off-by-one error in bitmap size check
ARM: 8402/1: perf: Don't use of_node after putting it
ARM: 8400/1: use virt_to_idmap to get phys_reset address
