I dont understand how the vmap change can break DRM.

The vmap patch only changes internal mm/vmalloc.c code (vmalloc() call

Anyway, Mitch (or Erik who's seeing the problem), can please revert the
vmap() change to check if its causing the mentioned problem?

The patch is attached. Apply it with -R.
