2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Peter Zijlstra <a.p.zijlstra@chello.nl>

commit 00540e5d54be972a94a3b2ce6da8621bebe731a2 upstream.

x86 stack traces are a piece of crap without frame pointers, and its not
like the 'performance gain' of not having stack pointers matters when you
selected lockdep.
