It also depends on Russell King's devel-stable branch. So the options to
apply it in case you are otherwise happy with it:

- apply on top of tip/irq/for-arm dropping the change to
arch/arm/kernel/entry-v7m.S and let me add that change seperately; or
- let it go through Russell's tree (the dependency on tip/irq/for-arm
doesn't stop the patch to be applied on that one, it just won't
compile); or
- wait until there is a tree that contains both branches; or
- merge the two trees and apply it on top of the merge.
