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

Normally, you will choose 'N' here.
-config DEBUG_STACKOVERFLOW
- bool "Check for stack overflows"
- depends on DEBUG_KERNEL
- help
- This option will cause messages to be printed if free stack space
- drops below a certain limit(2GB on MIPS). The debugging option
- provides another way to check stack overflow happened on kernel mode
- stack usually caused by nested interruption.
