Well I would prefer to have this patch merged (Cc'ing Tomasz).

There is a procedure to solve this branch dependency.
1. Create a patchset with only the changes in drivers/cpuidle (+ misc dt
stuff)
2. Send the patchset to me.
3. I create a branch with these patches (which will be merged in my
cpuidle next branch)
4. Merge this branch to a new branch (based on 3.17-rcX) and put on top
of that your changes for ARM[64]
5. Send the PR to Catalin and Arnd (one for each branch or one for both
arch)
I will ensure the base branch is not removed until the next merge window.
Does it sound good ?
