Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm

Pull ARM fixes from Russell King:
 "A set of ARM fixes:

   - fix an off-by-one error in the iommu DMA ops, which caused errors
     with a 4GiB size.

   - remove comments mentioning the non-existent CONFIG_CPU_ARM1020_CPU_IDLE
     macro.

   - remove useless CONFIG_CPU_ICACHE_STREAMING_DISABLE blocks, where
     this symbol never appeared in any Kconfig.

   - fix Feroceon code to cope with a previous change correctly (it
     incorrectly left an additional word in an assembly structure
     definition)

   - avoid a misleading IRQ affinity warning in the ARM PMU code for
     IRQs which are already affine to their CPUs.

   - fix the node name printed in the IRQ affinity warning"
