There are no platforms left which use arch_vm_get_page_prot(). Just drop
generic arch_vm_get_page_prot().

Add a new config ARCH_HAS_VM_GET_PAGE_PROT, which when subscribed enables a

protection_map[] is an array based construct that translates given vm_flags
combination. This array contains page protection map, which is populated by
the platform via [__S000 .. __S111] and [__P000 .. __P111] exported macros.
Primary usage for protection_map[] is for vm_get_page_prot(), which is
The bug is here:

The list iterator value 'p' will *always* be set and non-NULL by
