From: Ville Syrjälä <ville.syrjala at linux.intel.com>

I was looking at FIFO underruns a bit and came up with a few improvements to
the FIFO underrun reporting code. Mainly this should lead to detecting FIFO
a bit more more reliably on gmch platforms.

I also promoted the IVB/CPT uncleared FIFO underrun messages to errors
since that's what we do everywhere else as well.

Ville Syrjälä (5):
  drm/i915: Check for FIFO underuns when disabling reporting on gmch
    platforms
  drm/i915: Check for FIFO underruns at the end of modeset on gmch
  drm/i915: Convert uncleared FIFO underrun message to errors
  drm/i915: Simplify the uncleared FIFO underrun detection
  drm/i915: Shuffle fifo underrun disable/enable points for gmch
    platforms
