Subject: [PATCH] lockdep: require framepointers for x86
Date: Wed, 04 Mar 2009 12:48:15 +0100 [thread overview]

Subject: lockdep: require framepointers for x86
From: Peter Zijlstra <a.p.zijlstra@chello.nl>
Date: Wed Mar 04 12:27:27 CET 2009
Require framepointers for x86, because otherwise we'll be having empty stack
