[ Upstream commit fe0fde09e1cb83effcf8fafa372533f438d93a1a ]

I found that normally it is O_NONBLOCK but there are different value
for some arch.

/include/linux/net.h:
#ifndef SOCK_NONBLOCK
#define SOCK_NONBLOCK O_NONBLOCK
#endif

/arch/alpha/include/asm/socket.h:
#define SOCK_NONBLOCK 0x40000000

Use SOCK_NONBLOCK instead of O_NONBLOCK for kernel_accept().
