it is simply assumed this is unsigned long, which is simply incorrect.

At the moment this is simply an incongruity, however in future we plan to
change this type and therefore this change is a critical requirement for

Same comments as Vlastimil, you want to push vmflag_to_pte_pkey_bits
further to patch#2 and bring 

arch/powerpc/mm/book3s64/pgtable.c:pgprot_t vm_get_page_prot(unsigned long vm_flags)
