Original posting: http://lkml.kernel.org/r/[email protected] 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 <[email protected]> Reviewed-by: H.

If you say Y here, it will be possible to remotely debug the kernel
|
|
using gdb. This enlarges your kernel ELF image disk size by several
|
|
megabytes and requires a machine with more than 16 MB, better 32 MB
|
|
RAM to avoid excessive linking time. This is only useful for kernel
|
|
hackers. If unsure, say N.

that GDB prints them as program output, say 'Y'.
