Hi David,

After merging the dwmw2-iommu tree, today's linux-next build (i386
defconfig) failed like this:

In file included from drivers/gpu/drm/i915/i915_drv.h:50:0,
                 from drivers/gpu/drm/i915/i915_drv.c:34:
include/linux/intel-iommu.h:477:22: error: field 'notifier' has incomplete type
  struct mmu_notifier notifier;
                      ^

Caused by commit

  a7002bccff99 ("iommu/vt-d: Add intel_svm_{un,}bind_mm() functions")

I have added the following patch for today:
