drm-intel-next

Here's a pile of fixes on top of the stuff already in drm-core-next.

* Pile of mode setting fixes which eliminate a selection of bugs and other annoyances. Eliminates the 'stripey' effect when going from two to one monitor, makes hot-plug work after suspend/resume, turns off the pipe/plane in DPMS off.

* DP mode setting cleanups and pessimizations that should recover from unexpected situations better.

* HDMI info frame changes, including the addition of SPD (source product description) frames.

* RC6 enabled by default (again). Given that we don't understand why it doesn't work, and that we've found and fixed at least a couple of RC6-related bugs, maybe it works now? Prepare to see this reverted before 3.1 if we get regression reports (sigh).

The following changes since commit 5a96a899bbdee86024ab9ea6d02b9e242faacbed

Can you ack at least this one:

(i.e. d2b996ac698aebb28557355857927b8b934bb4f9)

for -stable? It fixes an annoying regression in 3.0.

Thanks,
Andy

I'm working on a set of patches for -stable; we've found a number of small patches that fix some fairly serious regressions.
