3.16.35-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Borislav Petkov <b...@suse.de>
commit f594bae08183fb6b57db55387794ece3e1edf6f6 upstream.
I'm surprised this remained undocumented since at least 2011. And it is
actually a very useful switch, as Steve and I came to realize recently.
Add the text from
2cba3ffb9a9d ("perf stat: Add -d -d and -d -d -d options to show more CPU
events")
which added the incrementing aspect to -d.
