One thing I noticed while staring at the ppgtt code recently is that
gen6 ppgtt cleanup kfrees the ppgtt struct, but gen8 code doesn't.
At that time it looked like the correct fix was moving the kfree()
out from the gen6 code into some common place. The reason being
that the gen8 code called the cleanup function during error handling
in the init paths. But I'm not sure if you've changed that with this
series. A quick scan of these patches tells me the leak is still
there at least.
