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
