[Nouveau] [PATCH v2 0/4] New instmem implementation for Tegra

[Alexandre Courbot]

Changes since v1:
- Timeout after 2ms on LTC flush/invalidate (nvgpu uses 1ms, but this is still
  small enough and leaves us on the safe side)
- Add convenience nvkm_wait() macros for waiting on register values

Alexandre Courbot (4):
  timer: re-introduce nvkm_wait_xsec macros
  ltc: add hooks for invalidate and flush
  ltc/gf100: add flush/invalidate functions
  instmem/gk20a: use direct CPU access
