Intel Stages More DRM Driver Changes For Linux 4.10

Two weeks back Intel submitted their first set of feature changes for Linux 4.10 to DRM-Next so that they can be staged for this next major kernel cycle. Coming in now is a second set of feature additions and other changes/improvements.

Found with this latest drm-intel-next pull is a GPU idling rework for suspend-and-resume, faster probing on resume, DisplayPort audio workarounds for "Gen9" hardware (such as Skylake), support for multiple timelines as prep work to their new scheduler, GuC log buffer support, and a wide range of other fixes throughout this open-source Direct Rendering Manager driver.

This secondary pull request changes around more than five thousand lines of code. Those interested in digging through the individual changes for this pull request -- which has already been honored and is now in DRM-Next until the 4.10 merge window -- can see this mailing list message.
