From 7e6735c3578e76c270a2797225a4214176ba13ef Mon Sep 17 00:00:00 2001 From: Cyril Chemparathy Date: Wed, 12 Sep 2012 14:05:58 -0400 Subject: /dev/mem: use phys_addr_t for physical addresses This patch fixes the /dev/mem driver to use phys_addr_t for physical addresses. This is required on PAE systems, especially those that run entirely out of >4G physical memory space.
