Move the code into drivers/oprofile/ so that SH can use it instead of the nearly identical copy of its OProfile code. The benefit of the backend is that it becomes necessary to only maintain one copy of the PMU accessor functions for each architecture, with bug fixes and new features benefiting both OProfile and perf. Note that I haven't been able to test these patches on an ARM board to see if I've caused any regressions. If anyone else could do that I'd appreciate it. This patch series is based on tip/master.
