[PATCH] drm/nouveu: fix swiotlb include

[Christian König]

The check for swiotlb has moved to nouveu_ttm.c, but we forgot to move
the include as well.

Hm drm-misc-next compiles fine with swiotlb enabled in config. Am I
blind or is this a merge problem with -rc1? If the latter need to give
Thomas a heads-up about that for the backmerge of -rc2.

It's a merge problem with linux-next Stephen pointed out.

And before you ask: Nope, I have no idea why drm-misc-next alone 
compiles fine either.

Anyway taking over the include is the right thing to-do. Can I please 
get an rb?

Thanks,
Christian.

Ah if we can apply this already to make sure the merge doesn't go
boom, then should be good to apply already :-)

Maybe smash your above explanation into the commit message too, for the record.

So this now broke drm-misc-next compilation on arm, which isn't great.
Please make sure you compile test stuff before pushing.

Since the proper fix is maybe stuck in the usual "drm abuses swiotlb
internals" bikeshed, maybe best if we push a fix to including limits.h
in nouveau and call it done? Also adding Maxime, who's trying to get
the backmerge through right now.

Well, I did compile tested it on x86_64 before pushing and all looked well.

Yeah, that is probably the best approach. I didn't realized that the 
include of limit.h needs to move as well.

Christian.
