From d1a1dc0be866219f7a613c6368c6a036b8eefe03 Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Mon, 1 Jul 2013 13:04:42 -0700 Subject: consolidate per-arch stack overflow debugging options Original posting: http://lkml.kernel.org/r/20121214184202.F54094D9@kernel.stglabs.ibm.com Several architectures have similar stack debugging config options. They all pretty much do the same thing, some with slightly differing help text. This patch changes the architectures to instead enable a Kconfig boolean, and then use that boolean in the generic Kconfig.debug to present the actual menu option. This removes a bunch of duplication and adds consistency across arches. Signed-off-by: Dave Hansen Reviewed-by: H.
