There's a large number of vm_get_page_prot(vma->vm_flags) invocations. Make life easier by introducing vma_get_page_prot() parameterised by the VMA. This also makes converting vm_get_page_prot() to vma_flags_t easier. Also update the userland VMA tests to reflect the change. No functional change intended.

One missed? drivers/gpu/drm/panthor/panthor_gem.c still has: vma->vm_page_prot = vm_get_page_prot(vma->vm_flags); Can use vma_get_page_prot(vma) too. [...]
