This patchset adds a tracepoint, error_repor_end, that is to be used by
KFENCE, KASAN, and potentially other bug detection tools, when they
print an error report.
One of the possible use cases is userspace collection of kernel error
reports: interested parties can subscribe to the tracing event via
tracefs, and get notified when an error report occurs.

v3:
 - dropped the sysfs interface for log collection
 - dropped error_report_start tracepoint
Just for record. This approach looks reasonable to me.
Thanks for removing the sysfs interface. It would have been
a potential can of worms.

I do not feel eligible to add any tag. I am neither familiar
with the tracepoint nor the KFENCE or KASAN code.
