We abstract the type of the VMA flags to vm_flags_t, however in may places
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
doing so.
Overall, this patch does not introduce any functional change.

Hopefully not causing a circular header include.

Is this change rather for patch 3? It's not changing vm_get_page_prot().
OTOH git grep shows me you missed:
arch/powerpc/mm/book3s64/pgtable.c:pgprot_t vm_get_page_prot(unsigned long
vm_flags)
With that sorted out, feel free to add:
