Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King: "Three fixes and a resulting cleanup for -rc2: - Andre Przywara reported that he was seeing a warning with the new cast inside DMA_ERROR_CODE's definition, and fixed the incorrect use. - Doug Anderson noticed that kgdb causes a "scheduling while atomic" bug. - OMAP5 folk noticed that their Thumb-2 compiled X servers crashed when enabling support to cover ARMv6 CPUs due to a kernel bug leaking some conditional context into the signal handler" * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: ARM: 8425/1: kgdb: Don't try to stop the machine when setting breakpoints ARM: 8437/1: dma-mapping: fix build warning with new DMA_ERROR_CODE definition ARM: get rid of needless #if in signal handling code ARM: fix Thumb2 signal handling when ARMv6 is enabled
