[RESEND] [PATCH v6 0/8] do not store GPU address in TTM

[Christian König]

I've pushed patches #1, #2 and #5-#8 of this series to drm-misc-next.

Only VMGFX and Nouveau are missing and I'm pretty close to just push 
them with my Acked-by since they should not contain any functional change.

Any objections?

Thanks,
Christian.
