Hi Russell,

Please pull these perf fixes for 3.2. Without them, modules trying to use
the PMU will not compile (I accidently dropped an EXPORT_SYMBOL) and, more
seriously, perf can be made to dereference NULL if the user tries to
schedule an event group.

Thanks to Tixy and Pawel for reporting the issues.

Cheers,

Will
