linux-next/arch/arc/Kconfig.debug
Dave Hansen d1a1dc0be8 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.

help
Write kernel log output directly into the VGA buffer or to a serial
port.
This is useful for kernel debugging when your machine crashes very
early before the console code is initialized. For normal operation
it is not recommended because it looks ugly and doesn't cooperate
with klogd/syslogd or the X server. You should normally N here,
unless you want to debug such a crash.
config 16KSTACKS
bool "Use 16Kb for kernel stacks instead of 8Kb"
help
If you say Y here the kernel will use a 16Kb stacksize for the
kernel stack attached to each process/thread. The default is 8K.
This increases the resident kernel footprint and will cause less
threads to run on the system and also increase the pressure
on the VM subsystem for higher order allocations.
