This appears to be because I access something declared as perf_event *[]
using something of type perf_event **. I plan on re-rolling these fixes
anyway as I found a problem with CONFIG_PREEMPT, so I'll add the
necessary casts to silence sparse to the series.

I don't think you've pulled my perf-split branch yet, so if you hold
fire on that I'll add some fixes to get rid of these warnings [I think I
noticed one of the issues before] and send another pull request in the
week.

Thanks!

Will
