UML - Fix boot crash
PATCH 13/14 UML - Fix boot crash
From 7ca5503f5ee32fb3cd6aa6eca21a8edfe09a7717 Mon Sep 17 00:00:00 2001
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.
