[PATCH] x86_64: Allow nesting of int3 by default for kprobes
This unbreaks recursive kprobes which didn't work anymore due to an earlier patch which converted the debug entry point to use an IST. This also allows nesting of the debug entry point too. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
