[RFC PATCH 00/13] SVM (share virtual memory) with HMM in nouveau
...ver code mmap's an area below (1 << 40). It's hard to avoid this,
given that user space needs access to the area (for filling out command
buffers and monitoring semaphores, that sort of thing). Then suballocate
from there using mmap's MAP_FIXED or (future-ish) MAP_FIXED_SAFE flags.
