number	441 (0x1b9)
abi	common
entry point	`sys_epoll_pwait2`

Registers

register	value
`a7`	441, the syscall number
`a0`	int epfd
`a1`	struct epoll_event *events
`a2`	int maxevents
`a3`	const struct __kernel_timespec *timeout
`a4`	const sigset_t *sigmask
`a5`	size_t sigsetsize
`a0`	the return value

Then run syscall 0 to enter the kernel.
