This patch consolidates the semtimedop Linux implementation in only one default file, sysdeps/unix/sysv/linux/semtimedop.c. If tries to use the direct syscall if it is supported, otherwise will use the old ipc multiplex mechanism. Checked on x86_64, i686, powerpc64le, aarch64, and armhf. * sysdeps/unix/sysv/linux/alpha/syscalls.list (semtimedop): Remove. * sysdeps/unix/sysv/linux/arm/syscalls.list (semtimedop): Likewise. * sysdeps/unix/sysv/linux/generic/syscalls.list (semtimedop): Likewise. * sysdeps/unix/sysv/linux/hppa/syscalls.list (semtimedop): Likewise. * sysdeps/unix/sysv/linux/ia64/syscalls.list (semtimedop): Likewise. * sysdeps/unix/sysv/linux/microblaze/syscalls.list (semtimedop): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (semtimedop): Likewise. * sysdeps/unix/sysv/linux/x86_64/syscalls.list (semtimedop): Likewise. * sysdeps/unix/sysv/linux/m68k/semtimedop.S: Remove file. * sysdeps/unix/sysv/linux/s390/semtimedop.c: Reorganize headers and add a comment about s390 syscall difference from default one. * sysdeps/unix/sysv/linux/semtimedop.c (semtimedop): Use semtimedop syscall if it is defined.
