[Intel-gfx] [PATCH 0/3] drm: Allow vblank interrupts during modeset and make the code less racy, take two

[ville.syrjala at linux.intel.com]

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

This series is a continuation of the earlier attempt [1]. The first two
patches from that series are still needed, but since they were unchanged
I didn't include them here. The rest of the original series should be
scrapped.

This time I dropped the 'reject' and 'vblank_always_enable_on_get' and
instead did things like Daniel suggested. This does change the behaviour
of blocking vblank waits for all drivers to return when the vblank interrupt
gets disabled, whereas the old series made everything purely opt-in. To fix
up the remaining drivers fully, someone needs to go and sprinkle the
drm_vblank_on() calls there. Daniel volunteered to do that, so I'm not going
to bother.
