[REGRESSION] nouveau: Memory corruption using nva3 engine for 0xaf
Hi Ben, Dave,
Since 3.5-rc0, I have been experiencing occasional screen corruption
on my MacBookAir3,1, using a GeForce 320M (nv50, 0xaf). The X driver
version is xf86-video-nouvea-1.0.1-1 (arch).
I do not know what the root problem is, but I have been able to
isolate the symptoms to the usage of nva3_copy.c. The patch below is
the least intrusive way I could find which kills the symptoms.
