There are some deprecated events listed by perf list. But we can't remove

Deprecated events are old names of renamed events. When an event gets
renamed the old name is kept around for some time and marked with
Deprecated. The newer Intel event lists in the tree already have these
So we need to keep them in the event list, but provide a new option to
show them. The new option is "--deprecated".
With this patch, the deprecated events are hidden by default but they can
be displayed when option "--deprecated" is enabled.
not sure it's wise to hide them, because people will not read man page
to find --deprecated option, they will rather complain right away ;-)
how about to display them as another topic, like:
I don't know if we add a new topic "deprecated" in perf list output, does
the old script need to be modified as well?
Say the events are moved to the "deprecated" section, I just guess the
script needs the modification.
That's just my personal guess. :)
i did not mean adding new topic all the way down,
just to display the deprecated events like that
