drm/i915 fixes for v5.2-rc3:
- fix mmap range checks
- fix gvt ppgtt mm LRU list access races
- fix selftest error pointer check
- fix a macro definition (pre-emptive for potential further backports)
- fix one AML SKU ULX status

UAPI Changes:
- Make mmap code more asynchronous. Avoid full SET_DOMAIN on GTT mmap pagefault,
  and flushes pages on acquisition instead. Moves some of the work from mmap fault
  time to execbuf time to avoid lock contention during mmap access.

  Has neutral to positive impact on perf as the flushing moves to execbuf time
  in real world workloads on the current known userspaces due to recycling of BOs.

  If there exist an unknown non-recycling userspace, they should explicitly do the
  SET_DOMAIN and not rely on kernel doing implicit SET_DOMAIN because swapout/in
  might have happenedt.

  From 2011: ff72145badb8 ("drm: dumb scanout create/mmap for intel/radeon (v3)")
