From 0947b2f31ca1ea1211d3cde2dbd8fcec579ef395 Mon Sep 17 00:00:00 2001 From: "Huang, Ying" <ying.huang@intel.com> Date: Wed, 30 Jan 2008 13:33:44 +0100 Subject: i386 boot: replace boot_ioremap with enhanced bt_ioremap - enhance bt_ioremap This patch makes it possible for bt_ioremap() to be used before paging_init(), via providing an early implementation of set_fixmap() that can be used before paging_init(). This way boot_ioremap() can be replaced by bt_ioremap().
