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 <dave@linux.vnet.ibm.com> Reviewed-by: H.

SPR_SR_DSX bit is status register bit indicating whether

OpenRISC architecture makes it optional to have it implemented

in hardware and the OR1200 does not have it.
