Later conversions use hw_pte_t in page-table checking, generic page-table helpers, and vmalloc interfaces. Include linux/pgtable_types.h from the headers that declare those interfaces before changing their types. For vmalloc.h, replace the direct asm/page.h include with linux/pgtable_types.h. The latter includes asm/page.h, so pgprot_t remains available. It also provides either the default alias or the opted-in hw_pte_t wrapper.
