You do know Linus' stance on enabling things by default which are not
ubiquitous, right?

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

I agree the sysfs exposure duplicates existing infrastructure, points
taken. However, tracking fatal hardware errors provides value at crash
analysis time—it lets us quickly determine whether a fatal hardware
error occurred during the kernel's lifetime, which is useful for
root-cause attribution.

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

For this, would you like to keep it in vmcore info (as of today), or
move to RAS subsystem?

You mean, would I like to pay attention to more patches than now?

Not really - I can barely manage as it is.
