[F][PATCH 0/1] Restrict xmon to read-only-mode if kernel is locked down (LP: 1863562)

This is a change to xmon (the power crash handler / pseudo-debugger)
to restrict it to read-only mode when the kernel is lockdown'ed,
otherwise it's trivial to drop into xmon and modify kernel data,
such as the lockdown state.
