Kudos for making these two paths more similar.
Not specific to *this* patch, but it's annoying to try to find
tracepoint implementations. I guess it's
TRACE_EVENT(non_standard_event, ...) in include/ras/ras_event.h.
This has the same prototype as log_non_standard_event(), so
could extlog_print() be made a little bit more like ghes_do_proc() by
using log_non_standard_event() instead of trace_non_standard_event()
directly?
