[Intel-gfx] [PATCH 00/16] FBC bug fixes

[Paulo Zanoni]

Hello

This series contains tons of bug fixes for FBC. Some of the patches on this
series have seen the mailing list a few times already. With this series applied,
my BDW machine passes all the FBC tests that are on IGT.

This means we could even try to enable FBC on BDW by default, but I won't put
this patch as part of the series since I want QA to confirm everything passes
before we make this move. In the meantime, there are some optimizations I want
to do, and SKL to fix.

Thanks,
Paulo
