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.

Unmap pages from the kernel linear mapping after free_pages().

This results in a large slowdown, but helps to find certain types
|
|
of memory corruptions.

If you say Y here the resulting kernel image will be slightly larger
|
|
and slower, but it will give very useful debugging information.
|
|
If you don't debug the kernel, you can say N, but we may not be able
|
|
to solve problems without frame pointers.
