+Subject: perf stat: Document --detailed option
+
+From: Borislav Petkov <bp@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.
