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
