in fact the way i implemented it in my tree:

#define in_atomic_rt() (!oops_in_progress && (in_atomic() || irqs_disabled()))

still enables crash messages to make it to fbcon. So the only thing
skipped will be non-fatal messages printed from 'raw' critical sections.
(which are very rare in PREEMPT_RT kernels).
