rt_sigtimedwait

synchronously wait for queued signals

sys_rt_sigtimedwait_time32(const sigset_t *uthese, siginfo_t *uinfo, const struct old_timespec32 *uts, size_t sigsetsize)

register	value
`r3`	177, the syscall number
`r4`	const sigset_t *uthese
`r5`	siginfo_t *uinfo
`r6`	const struct old_timespec32 *uts
`r7`	size_t sigsetsize
`r0`	the return value

Then run trapa #31 to enter the kernel.
