Hi,
I occasionally build the odd program against raw perf and use perf.h for
this.
Now I find that no longer works because of:
52502bf201a85 ("perf tests: Add framework for automated perf_event_attr tests")
So revert the hunk touching on perf.h.
Also, it seems to be for snake shit only, and snakes stink, except on a
plane :-)
