The __ASSUME_SOCKETCALL macro in kernel-features.h is no longer used for anything. (It used to be used in defining other macros related to accept4 / recvmmsg / sendmmsg availability, but the code in that area was simplified once we could assume a kernel with those features, whether through a syscall or through socketcall, so allowing those functions to be handled much like other socket operations, without requring __ASSUME_SOCKETCALL.) This patch removes that unused macro. (Note: once we can assume a Linux 4.4 or later kernel, much of the support for using socketcall at all can be removed from glibc, although a few functions may need that support in glibc for longer.) Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/kernel-features.h: Remove comment about __ASSUME_SOCKETCALL. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_SOCKETCALL): Remove. * sysdeps/unix/sysv/linux/m68k/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/microblaze/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/s390/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/sparc/kernel-features.h (__ASSUME_SOCKETCALL): Likewise.
