	Initializes a per-thread performance context.
void	perf_init (void)
	Initializes the performance driver.
void	perf_interrupt_begin (cpu_t *self)
	Called at the beginning of an interrupt to update cpu performance data.
void	perf_interrupt_end (cpu_t *self)
	Called at the end of an interrupt to update cpu performance data.
void	perf_syscall_begin (void)
	Called at the beginning of a syscall to update process performance data.
void	perf_syscall_end (void)
