Fix __ASSUME_SENDMMSG issues (bug 16611).
Similar to the issues for accept4 and recvmmsg, __ASSUME_SENDMMSG is also confused about whether it relates to function availability or socketcall operation availability, and the conditions for the definition are always wrong (sendmmsg appeared in Linux kernel 3.0, not 2.6.39); this is now bug 16611. This patch splits the macro into separate macros like those for accept4 and recvmmsg, defining them for appropriate kernel versions. Tested x86_64, including that disassembly of the installed shared libraries is unchanged by this patch. [BZ #16611] * sysdeps/unix/sysv/linux/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x030000 && __ASSUME_SOCKETCALL] (__ASSUME_SENDMMSG_SOCKETCALL): Define. [__LINUX_KERNEL_VERSION >= 0x030000 && (__i386__ || __x86_64__ || __powerpc__ || __sh__ || __sparc__)] (__ASSUME_SENDMMSG_SYSCALL): Likewise. [__i386__ || __powerpc__ || __sh__ || __sparc__] (__ASSUME_SENDMMSG_SYSCALL_WITH_SOCKETCALL): Likewise. [__ASSUME_SENDMMSG_SOCKETCALL || __ASSUME_SENDMMSG_SYSCALL] (__ASSUME_SENDMMSG): Define instead of using previous [__LINUX_KERNEL_VERSION >= 0x020627] condition. * sysdeps/unix/sysv/linux/aarch64/kernel-features.h (__ASSUME_SENDMMSG_SYSCALL): Define. * sysdeps/unix/sysv/linux/alpha/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x030200] (__ASSUME_SENDMMSG_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/arm/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x030000] (__ASSUME_SENDMMSG_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/ia64/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x030000] (__ASSUME_SENDMMSG_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/internal_sendmmsg.S [__ASSUME_SOCKETCALL && !__ASSUME_SENDMMSG_SYSCALL_WITH_SOCKETCALL && !__ASSUME_SENDMMSG_SYSCALL] (__NR_sendmmsg): Undefine. [__ASSUME_SENDMMSG]: Change conditionals to [__ASSUME_SENDMMSG_SOCKETCALL]. * sysdeps/unix/sysv/linux/microblaze/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x030300] (__ASSUME_SENDMMSG_SYSCALL): Define. * sysdeps/unix/sysv/linux/mips/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x030100] (__ASSUME_SENDMMSG_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/sendmmsg.c [__ASSUME_SOCKETCALL && !__ASSUME_SENDMMSG_SYSCALL_WITH_SOCKETCALL && !__ASSUME_SENDMMSG_SYSCALL] (__NR_sendmmsg): Undefine. [!__ASSUME_SENDMMSG]: Change conditional to [!__ASSUME_SENDMMSG_SOCKETCALL]. * sysdeps/unix/sysv/linux/tile/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x030000] (__ASSUME_SENDMMSG_SYSCALL): Define. * sysdeps/unix/sysv/linux/hppa/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x030100] (__ASSUME_SENDMMSG_SYSCALL): Define.
