Subject: [git pull] drm nouveau runpm and mst fixes

Hi Linus,

I'm sending this separately as it's a bit larger than I generally like
for one driver, but it does contain a bunch of make my nvidia laptop
not die (runpm) and a bunch of make my docking station and monitor
display stuff (mst) fixes.

Lyude has spent a lot of time on these, and we are putting the fixes
into distro kernels as well asap, as it helps a bunch of standard
Lenovo laptops, so I'm fairly happy things are better than they were
before these patches, but I decided to split them out just for
clarification.

I'll have a normal -fixes pull tomorrow most likely.

Dave.
