[Qemu-devel] [PATCH 1/4] linux-user: Fix support for the SIOCATMARK and SIOCGPGRP ioctls for eXtensa

[Aleksandar Markovic]

From: Aleksandar Markovic <address@hidden>

Fix support for the SIOCATMARK and SIOCGPGRP ioctls for eXtensa by
correcting corresponding macro definition.

Values for TARGET_SIOCATMARK and TARGET_SIOCGPGRP are determined by
Linux kernel. Following relevant lines are from kernel source tree:

arch/ia64/include/uapi/asm/sockios.h:#define SIOCATMARK    0x8905
arch/mips/include/uapi/asm/sockios.h:#define SIOCATMARK    _IOR('s', 7, int)
arch/parisc/include/uapi/asm/sockios.h:#define SIOCATMARK  0x8905
arch/sh/include/uapi/asm/sockios.h:#define SIOCATMARK      _IOR('s', 7, int)
arch/xtensa/include/uapi/asm/sockios.h:#define SIOCATMARK  _IOR('s', 7, int)
arch/alpha/include/uapi/asm/sockios.h:#define SIOCATMARK   _IOR('s', 7, int)
arch/sparc/include/uapi/asm/sockios.h:#define SIOCATMARK   0x8905
include/uapi/asm-generic/sockios.h:#define SIOCATMARK      0x8905

arch/ia64/include/uapi/asm/sockios.h:#define SIOCGPGRP     0x8904
arch/mips/include/uapi/asm/sockios.h:#define SIOCGPGRP     _IOR('s', 9, pid_t)
arch/parisc/include/uapi/asm/sockios.h:#define SIOCGPGRP   0x8904
arch/sh/include/uapi/asm/sockios.h:#define SIOCGPGRP       _IOR('s', 9, pid_t)
arch/xtensa/include/uapi/asm/sockios.h:#define SIOCGPGRP   _IOR('s', 9, pid_t)
arch/alpha/include/uapi/asm/sockios.h:#define SIOCGPGRP    _IOR('s', 9, pid_t)
arch/sparc/include/uapi/asm/sockios.h:#define SIOCGPGRP    0x8904
include/uapi/asm-generic/sockios.h:#define SIOCGPGRP       0x8904

It is visible that eXtensa should have the same definitions as
alpha, mips and sh4 already do. This patch brings that to the
accurate state.
