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.

help
|
|
If you say Y here the kernel will use a 4Kb stacksize for the
|
|
kernel stack attached to each process/thread. This facilitates
|
|
running more threads on a system and also reduces the pressure
|
|
on the VM subsystem for higher order allocations. This option
|
|
will also use IRQ stacks to compensate for the reduced stackspace.

help
|
|
If you say Y here the kernel will use the Meta hardware trace
|
|
unit to output information about function entry and exit that
|
|
can be used by a debugger for profiling and call-graphs.

help
|
|
If you say Y here the kernel will write poison data to the
|
|
catch buffer registers on kernel entry. This will make any
|
|
problem with catch buffer handling much more apparent.
