RAS user space tools like rasdaemon which base on trace event, could
receive mce error event, but no memory recovery result event. So, I want
to add this event to make this scenario complete.
This patch add a event at ras group for memory-failure.
The output like below:
# tracer: nop
#
# entries-in-buffer/entries-written: 2/2 #P:24
#
# _-----=> irqs-off
# / _----=> need-resched
# | / _---=> hardirq/softirq
# || / _--=> preempt-depth
# ||| / delay
# TASK-PID CPU# |||| TIMESTAMP FUNCTION
# | | | |||| | |
