Since we have the ttm and gem vma managers using a subset of the file address space for objects, and these start at 0x100000000 they will overflow the new mmap checks. I've checked all the mmap routines I could see for any bad behaviour but overall most people use GEM/TTM VMA managers even the legacy drivers have a hashtable.
