Since commit 69aad6f1(perf tools: Introduce event selectors), only
perf_event_attr::type and ::config are passed to event selector, which
makes perf tool not work correctly.
For example, PEBS does not work because perf_event_attr::precise_ip is
not passed to the syscall.

Right, thanks for the fix, Ingo, I'm adding this to my perf/core tree.
