[PATCH 0/3] Stable backports of gntdev fixes

I backported the recent gntdev patches to stable branches before 5.15. The first patch is a prerequisite for the other backports. The second patch should apply cleanly to all stable branches, but the third only applies to 5.10 as it requires mmu_interval_notifier_insert_locked().
