[Intel-gfx] [PATCH 0/4] ppgtt: ring initialization fixes

[Mika Kuoppala]

With this series I can get reliable ring initialization
on my gen7 and ppgtt=2. No page faults nor rings running
wild across address space. Prerequisite for testing
dynamic page table series on gen7.

Chris Wilson (2):
  drm/i915: Detect page faults during hangcheck
  drm/i915: Reorder hw init to avoid executing with invalid context/mm
    state

Mika Kuoppala (2):
  drm/i915: Introduce ring->start_ring()
  drm/i915: Stop rings before cleaning up on reset
