From 0eb25b619699270a8af95c2f76791fd6c4b52972 Mon Sep 17 00:00:00 2001

Subject: [PATCH] common: Make sure arch-specific map_sysmem() is defined

In the case where the arch defines a custom map_sysmem(), make sure that
including just mapmem.h is sufficient to have these functions as they
are when the arch does not override it.

Also split the non-arch specific functions out of common.h
