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.

Mark the kernel read-only data as write-protected in the pagetables,
|
|
in order to catch accidental (and incorrect) writes to such const
|
|
data. This option may have a slight performance impact because a
|
|
portion of the kernel code won't be covered by a TLB anymore.
|
|
If in doubt, say "N".
