timerfd_settime64

timers that notify via file descriptors

sys_timerfd_settime(int ufd, int flags, const struct __kernel_itimerspec *utmr, struct __kernel_itimerspec *otmr)

register	value
`r2`	411, the syscall number
`r4`	int ufd
`r5`	int flags
`r6`	const struct __kernel_itimerspec *utmr
`r7`	struct __kernel_itimerspec *otmr
`r2`	the return value

Then run trap to enter the kernel.

Same syscall on other architectures
