You do know Linus' stance on enabling things by default which are not

Logging hw errors in vmcore is really necessary to be enabled everywhere?

Yes, that's why you put it in vmcore. You can't read sysfs if you encounter
a fatal hw error.

You mean, would I like to pay attention to more patches than now?
Not really - I can barely manage as it is.
