Andreas Kling ea500dd3e3 Kernel: Start work on full system profiling :^) ...

The superuser can now call sys$profiling_enable() with PID -1 to enable
profiling of all running threads in the system. The perf events are
collected in a global PerformanceEventBuffer (currently 32 MiB in size.)

The events can be accessed via /proc/profile
