[PATCH v5 0/2] Restrict BMG to use 64K pages for scanout buffers

[Zbigniew Kempczyński]

According to talk to UMD teams they've asked to adjust allocation
for scanout buffer transparently to required by display alignment.
Previously we agreed we require explicitly aligned size, what was
relaxed in creating dumb bo. I decided to relax this requirement
for scanout as well to avoid changes from UMD side.

+Thomas, +Maarten for their statement about change
For reference about explicit uAPI change please take a look
to v3.

v2: Limit restriction to BMG
v3: Expose display alignment config to userspace
v4: Drop display alignment config
    Handle buffer size adjustment transparently in the kernel
v5: Rebase to current drm-tip
