Read taht, and two things aren't clear to me: first, there a long
discussion of fence for andoroid. Secon, at the bottom, it's still showing
include/Linux/fence.h
I've also just d/l the current proprietary driver from NVida - I had 375,
this is 384, and when I decide, sometime this afternoon, to reboot, come
up with the new kernel, I'll try building that.
