Revision c97d20a6c51067a38f53680d9609b4cf2867d077 authored by Andi Kleen on 28 July 2006, 12:44:57 UTC, committed by Linus Torvalds on 29 July 2006, 02:28:00 UTC
Similar patch to earlier x86-64 patch. When the dwarf2 unwinder fails dump the left over stack with the old unwinder. Also some clarifications in the headers. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
