* arch_debug_get_stack_trace():

- Replaced the "userOnly" parameter by a "flags" parameter, that allows to
    specify kernel and userland stack traces individually.
  - x86, m68k: Don't always skip the first frame as that prevents the caller
    from being able to record its own address.
* capture_tracing_stack_trace(): Replaced the "userOnly" parameter by
  "kernelOnly", since one is probably always interested in the kernel stack
  trace, but might not want the userland stack trace.
* Added stack trace support for VM cache kernel tracing.
