Oh I did not realize this series is about this, perhaps because I did 
not see 1/5 which maybe had some more obvious clues. :)

Great, that means if we decide to merge "drm/i915: Consider plane 
rotation when calculating stride in skl_do_mmio_flip" and 
"kms_rotation_crc: Exercise page flips with 90 degree rotation" we would 
have working rotated legacy page flip with a test case.

Tvrtko

Pulled all 5 into drm-misc, thanks.

Matt, can you please push these igt patches and double-check that we have
subtests to catch the viewport confusion here?

Thanks, Daniel

Looks like Thomas already beat me to pushing the relevant i-g-t patches
(both the one I wrote and the one Tvrtko wrote), so I think we're
covered there.

Thanks.
