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
`r12`	177, the syscall number
`r5`	const sigset_t *uthese
`r6`	siginfo_t *uinfo
`r7`	const struct old_timespec32 *uts
`r8`	size_t sigsetsize
`r3`	the return value

Then run brki r14,8 to enter the kernel.
