From 7c1fed03b9fa32d4323d5caa6a9c7dcdd7eba767 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Wed, 23 Jul 2008 11:46:50 -0400 Subject: UML - Fix boot crash My copying of linux/init.h didn't go far enough. The definition of __used singled out gcc minor version 3, but didn't care what the major version was. This broke when unit-at-a-time was added and gcc started throwing out initcalls. This results in an early boot crash when ptrace tries to initialize a process with an empty, uninitialized register set.
