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.
