From c0a18111e571138747a98af18b3a2124df56a0d1 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Tue, 6 May 2008 17:09:27 -0700 Subject: [PATCH] Revert "uml: fix gcc problem" This reverts commit 22eecde2f9034764a3fd095eecfa3adfb8ec9a98. Uli reports that it breaks UML on x86-64 with the Fedora 8 gcc (gcc 4.1.2), causing a crash on startup. See http://marc.info/?l=linux-kernel&m=121011722806093&w=2 for a trace.
