Subject: [PATCH 1/7] perf: fix prototype of find_pmu_context
For some reason find_pmu_context is defined as returning void* rather
than a __percpu struct perf_cpu_context*. As all the requisite types are
defined in advance there's no reason to keep it that way.
This patch modifies the prototype of pmu_find_context to return a
__percpu struct perf_cpu_context*.
