Brian Gianforcaro ccdcb6a635 Kernel: Add PerformanceManager static class, move perf event APIs there
The current method of emitting performance events requires a bit of
boiler plate at every invocation, as well as having to ignore the
return code which isn't used outside of the perf event syscall. This
change attempts to clean that up by exposing high level API's that
can be used around the code base.
