[PATCH] x86_64: Separate CONFIG_UNWIND_INFO from CONFIG_DEBUG_INFO
As a follow-up to the introduction of CONFIG_UNWIND_INFO, this separates the generation of frame unwind information for x86-64 from that of full debug information. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
