| |
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.
