I find it a bit unfair that maintainers of architectures that have huge companies

PREEMPT isn't something new. Also, I don't think the arch part for
actually supporting it is particularly hard, mostly it is sticking the
preempt_schedule_irq() call in return from interrupt code path.
If you convert the arch to generic-entry (a much larger undertaking)
then you get this for free.
If the conversion isn't hard, why is the first reflex the urge to remove an architecture
instead of offering advise how to get the conversion done?
