-Subject: [PATCH 014/103] kaiser: tidied up kaiser_add/remove_mapping slightly
-
-Yes, unmap_pud_range_nofree()'s declaration ought to be in a
-header file really, but I'm not sure we want to use it anyway:
-so for now just declare it inside kaiser_remove_mapping().
-And there doesn't seem to be such a thing as unmap_p4d_range(),
-even in a 5-level paging tree.
