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

Pull ARM fixes from Russell King:
 "Three further fixes for ARM.

  Alexandre Courbot was having problems with DMA allocations with the
  GFP flags affecting where the tracking data was being allocated from.
  Vladimir Murzin noticed that the CPU feature code was not entirely
  correct, which can cause some features to be misreported"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  ARM: 8564/1: fix cpu feature extracting helper
  ARM: 8563/1: fix demoting HWCAP_SWP
  ARM: 8551/2: DMA: Fix kzalloc flags in __dma_alloc
