There is no point in differentiating between a range for which there
is not even a directory (and thus entries) and empty entry (pte_none()
or pmd_none() returns true).

There is no point in differentiating between a range for which there
is not even a directory (and thus entries) and empty entry (pte_none()
or pmd_none() returns true).
Simply drop the distinction ie remove HMM_PFN_EMPTY flag and merge now
duplicate hmm_vma_walk_hole() and
