[Intel-gfx] [PATCH 00/21] ppgtt cleanups / scratch merge (V2)

[Mika Kuoppala]

Hi,

I have replaced patch 2 from v1 series with version
that preallocates top level pdp structure with 32bit addressing
on architectures that have problems with pdp tlb flushes.

All issues raised with v1 should be addressed by this series.
Ville also noticed that copying scratch structures means unnecessary read
as we can straight out fill them. This change among others
triggered alot of rebasing thus new series.

I also included one patch that makes our bitops nonatomic.

Thanks,
-Mika
