Seems like it didn't have a chance to sit in -next, which is somewhat understandable given that it's considered a bugfix and it indeed fixed the bug it was meant to. i'm out of time to debug this tonight (I noticed the failures as I was heading to bed and figured I'd at least bisect them), so I wouldn't mind seeing a revert of the ARM side change of ad6492b80f until it's been sorted out so we keep bisectabilty intact for the rest of the kernel.
