Merge branch 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
"Two areas addressed by these fixes:
- Fixes from Dave Martin for the signal frames that were broken with
certain configurations. No one noticed until recently.
- More kexec fixes to ensure that the crashkernel region is correctly
allocated, and a fix for the location of the device tree when
several kexec kernels are loaded"
