From 78c86e5e5691fc84d5fbea0cd4ac7147e87b7490 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Thu, 10 Sep 2009 10:09:38 -0700 Subject: x86: split __phys_addr out into separate file Split __phys_addr out into its own file so we can disable -fstack-protector in a fine-grained fashion. Also it doesn't have terribly much to do with the rest of ioremap.c.
