If you have a hard time finding a cross compiler for this, there's some
nommu arm platforms. I used that for compile teesting nommu support
recently.
If it's not that, then it's something specific with that config for
sure.
Also looking a the tree, there's no ack from Andrew Morton. For merging
stuff that's not maintained in drm-misc (and definitely for stuff
outside
of drm maintained tree) we need an ack from the right maintainer.
Ok, going to revert from drm-misc-next then.
Any objections that I use an Acked-by: Daniel Vetter
and the original Link tags for the revert?
Christian.
Thanks,
Christian.
I'd say make sure he's ok before we dig an even deeper hole here.
