Include request for reset-rework branch.

Hi Dave,

if nobody has a last moment concern please include the following patches in drm-next.

Except for some minor fixes they have already been on the list for quite some time, but I intentional left out the debugfs related patches cause we haven't finished the discussion about them yet.

If you prefer to merge them directly, I also made them available as reset-rework branch here: git://people.freedesktop.org/~deathsimple/linux

Cheers, Christian.
