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.

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.
