Include request for reset-rework branch v4

Hi Dave,

there still seems to be the need for some further discussion about the SA code, so I again split that out of the patchset and tested the result a bit.

Most of the stuff still works fine without those offending changes, so to avoid mailing around unrelated and already reviewed patches, I request the include the following 17 patches into drm-next.

If you prefer to merge they are also available from git://people.freedesktop.org/~deathsimple/linux branch reset-rework.

Cheers, Christian.
