This just converts the generic vm_get_page_prot() implementation into a new
macro i.e DECLARE_VM_GET_PAGE_PROT which later can be used across platforms
when enabling them with ARCH_HAS_VM_GET_PAGE_PROT. This does not create any
functional change.

I think the comment above protection_map[16] in mm/mmap.c should be 
moved here.

Sure, makes sense. Will move.
