Both are:
Tested-by: Kenneth Graunke <kenneth@whitecape.org>

I tested them using DRI3/Present + UXA and DRI3/Present + Glamor on Haswell GT3e.
1. Plug external 2560x1440 DisplayPort monitor into laptop.
2. echo 'exec startkde' > ~/.xinitrc
3. startx
4. xrandr --output DP1 --auto

This used to result in DP1 switching to 2560x1440, but KWin getting stuck waiting on a buffer idle event that never came, so you'd only see a 1920x1080 screen in the top left corner of the display, with either black or white bars in the other area.  Other than the mouse cursor, nothing worked.

With these patches, X works as expected.  Thanks for the fixes, Keith!
