I already acked it: https://lkml.org/lkml/2015/4/23/161 so it will be picked up for 4.2. Will

Which tree is at applied to? I'm not seeing it in -next, and couldn't find it in any branches of the arm64 tree[1]. Sorry to pester, I'm just looking to cherry-pick it from it's proper upstream for testing with a stable/3.18 based kernel. Thanks, Kevin [1] https://git.kernel.org/cgit/linux/kernel/git/arm64/linux.git/

I don't think Catalin has started putting together our for-next/core branch yet, but I'd expect it to appear there when he picks it up. Will
