perf_event_open

set up performance monitoring

sys_perf_event_open(struct perf_event_attr *attr_uptr, pid_t pid, int cpu, int group_fd, unsigned long flags)

register	value
`d0`	332, the syscall number
`d1`	struct perf_event_attr *attr_uptr
`d2`	pid_t pid
`d3`	int cpu
`d4`	int group_fd
`d5`	unsigned long flags
`d0`	the return value

Then run trap #0 to enter the kernel.

Same syscall on other architectures
