I think we are talking about two different issues here. My issue is not
a compilation failure, it is an incorrect merge resolution that is
happening in -next because of two independent changes in the drm and
powerpc tree, the thread below should have more information.

I do not think this is something that either tree can solve
independently of each other, -next has to resolve the conflict correctly
(which is what I point out in the message above) and a note of it should
be passed along to Linus so it can be resolved correctly in mainline
when the time comes.
