This seems to have been merged by Linus tonight as ad6492b80f, and it
had fallout on ARM systems (boot failures with no console output on
all but 5 of my machine/config combos).

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.


Thanks,

-Olof
