From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Here's a new version of the GTT remapping series.
Changes since last time:
- Split up some code shuffling from the main patch
- Made the dumb stride alignment proper
- Finished the test case
- Fixed a few bugs found in testing
The one thing I didn't do is make remapping always happen.
The main reason is that it would break FBC, and I don't
want to rewrite the FBC code right now.
Test-with: 20190508162906.20808-1-ville.syrjala@xxxxxxxxxxxxxxx
