Hi all,

After merging the drm-intel tree, today's linux-next build (i386 defconfig)
produced this warning:

drivers/gpu/drm/i915/i915_gem_gtt.c: In function 'gen8_ppgtt_init':
drivers/gpu/drm/i915/i915_gem_gtt.c:954:22: warning: large integer implicitly truncated to unsigned type [-Woverflow]
  ppgtt-> = 1ULL << 32;

Introduced by commit 5c5f645773b6 ("drm/i915: Unify aliasing ppgtt
handling").  "total" is a size_t, so unsigned 32 bit on i386.
