commit 38797a33117222dadbc89e5f21ed8cd5deef9bea

Make TearFree effective with PRIME slave scanout
TearFree can now prevent tearing with any possible display
configuration.
Note that there may still be inter-GPU tearing if the primary GPU uses
a different driver.
v2:
* Also test dirty->slave_dst in radeon_prime_scanout_do_update

commit eda1f3df6aaed683036369fe8820da4dac3c2ae2
Author: Michel Dänzer <michel.daenzer at amd.com>
Date: Thu Sep 1 12:54:13 2016 +0900
Synchronize scanout pixmaps for TearFree
Copy the damaged areas which are still valid in the other scanout pixmap
from there, then only copy the remaining damaged area from the screen
pixmap.
This is slightly more efficient (only needs one Damage record instead of
two, and only needs to copy each screen update across PCIe once with
ShadowPrimary and a discrete GPU), and will be significantly more
efficient for PRIME with the following change.
