Hi Ingo,
I have a box where "perf top" shows no data. I get the header, but it
never shows anything. I bisected it down to this commit.

perf tools: Default to 1 KHz auto-sampling freq events
Which, besides the whitespace clean ups is simply:
-static int freq = 0;
+static int freq = 1000; /* 1 KHz */
Which, BTW, whitespace clean ups would have been nicer in a separate
patch. It was a bit of a PITA to find what actually changed.
Peter tells me that the freq stuff is a bit fragile. Note, latest pref
top works on other boxes. Just not this one.
