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
`rax`	1073742122, the syscall number
`rdi`	struct perf_event_attr *attr_uptr
`rsi`	pid_t pid
`rdx`	int cpu
`r10`	int group_fd
`r8`	unsigned long flags
`rax`	the return value

Then run syscall to enter the kernel.

Same syscall on other architectures
