Comment # 2 on bug 1084326 from Takashi Iwai

Now looking through the recent KVM changes in SLE15 branch, I stumbled on
  patches.suse/KVM-update-to-new-mmu_notifier-semantic-v2.patch

Alex, is it safe to apply as is?

This removes the invalidage_page mmu notifier in KVM, but I thought this
assumes the prerequisite changes in the MMU notifier core side:
