1. Fix OOM: Count memory usage only when allocation succeeded 2. Fix OOM: Make user allocation fail when memory is running out 3. Fix OOM: Move rusage_init() before numa_init() 4. Cleanup: Rename ihkconfig/ihkosctl functions 5. Cleanup: Pass event type to eventfd() 6. Cleanup: arch/.../rusage.h --> arch/.../arch_rusage.h
