Hi all,

Just a minor update, pulling in Xiongfeng's fix as a basis for the
subsequent patches moving that code around, and the Tegra DRM patch
previously posted separately. Plus commenting the subtlety in the AMD
pagetable code so it's hopefully easier to remember in future.

Given that no major issues have surfaced so far, hopefully this is on
track for 5.17 in parallel with the slab rework.

Thanks,
Robin.
