rmap: do not call mmu_notifier_invalidate_page() under ptl
MMU notifiers can sleep, but in page_mkclean_one() we call
mmu_notifier_invalidate_page() under page table lock.
Let's instead use mmu_notifier_invalidate_range() outside
page_vma_mapped_walk() loop.
[[email protected]: try_to_unmap_one() do not call mmu_notifier under ptl]
