Hi Andrew,

After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) failed like this:

/home/sfr/next/next/mm/hmm.c:202:2: error: unknown field 'invalidate_page' specified in initializer
  .invalidate_page = hmm_invalidate_page,
  ^
/home/sfr/next/next/mm/hmm.c:202:21: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .invalidate_page = hmm_invalidate_page,
                     ^

Caused by commit

  b49705c24406 ("mm/hmm/mirror: mirror process address space on device with HMM helpers")

interacting with commit

  5f32b265400d ("mm/mmu_notifier: kill invalidate_page")

from Linus' tree.

I have disabled CONFIG_HMM_MIRROR for today.
