OK... I finished the bisect:
09120d4e88b13967d44d46280fb74d3ac4ac2f73 is the first bad commit
commit 09120d4e88b13967d44d46280fb74d3ac4ac2f73
Author: Michel Thierry <michel.thierry at intel.com>

drm/i915: Remove unnecessary gen8_clamp_pd
gen8_clamp_pd clamps to the next page directory boundary, but the macro
gen8_for_each_pde already has a check to stop at the page directory
boundary.
Furthermore, i915_pte_count also restricts to the next page table
boundary.
v2: Rebase after Mika's ppgtt cleanup / scratch merge patch series.
