From beacfaac3f23b30814aafee37a055257c7062ef3 Mon Sep 17 00:00:00 2001 From: "Huang, Ying" Date: Wed, 30 Jan 2008 13:33:44 +0100 Subject: [PATCH] x86 32-bit boot: rename bt_ioremap() to early_ioremap() This patch renames bt_ioremap to early_ioremap, which is used in x86_64. This makes it easier to merge i386 and x86_64 usage.
