linux-user: Add support for SIOCSPGRP ioctl for all targets
Add support for setting the process (or process group) to receive SIGIO
or SIGURG signals when I/O becomes possible or urgent data is available,
using SIOCSPGRP ioctl.
The ioctl numeric values for SIOCSPGRP are platform-dependent and are
determined by following files in Linux kernel source tree:
arch/ia64/include/uapi/asm/sockios.h:#define SIOCSPGRP 0x8902
arch/mips/include/uapi/asm/sockios.h:#define SIOCSPGRP _IOW('s', 8, pid_t)
arch/parisc/include/uapi/asm/sockios.h:#define SIOCSPGRP 0x8902
arch/sh/include/uapi/asm/sockios.h:#define SIOCSPGRP _IOW('s', 8, pid_t)
arch/xtensa/include/uapi/asm/sockios.h:#define SIOCSPGRP _IOW('s', 8, pid_t)
arch/alpha/include/uapi/asm/sockios.h:#define SIOCSPGRP _IOW('s', 8, pid_t)
arch/sparc/include/uapi/asm/sockios.h:#define SIOCSPGRP 0x8902
include/uapi/asm-generic/sockios.h:#define SIOCSPGRP 0x8902
Hence the different definition for alpha, mips, sh4, and xtensa.
