From 789d03f584484af85dbdc64935270c8e45f36ef7 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 30 Jun 2009 11:52:23 +0100 Subject: x86: Fix fixmap ordering The merge of the 32- and 64-bit fixmap headers made a latent bug on x86-64 a real one: with the right config settings it is possible for FIX_OHCI1394_BASE to overlap the FIX_BTMAP_* range.
