| bool "Use 4Kb for kernel stacks instead of 8Kb"
| depends on DEBUG_KERNEL
| 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.
| bool "Output Meta real-time trace data for function entry/exit"
| 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.
| bool "Poison catch buffer contents on kernel entry"
| 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.
