Although defined in initial TLS/NPTL ABI for m68k and ColdFire [1], kernel support was never pushed upstream. This patch removes the unused m68k vDSO support. Checked with a build against m68k and m68k-coldfire and some basic tests on ARAnyM. * sysdeps/unix/sysv/linux/m68k/Makefile (sysdep_routines, sysdep-rtld-routines): Remove rules. * sysdeps/unix/sysv/linux/m68k/Versions (libc) [GLIBC_PRIVATE]: Remove __vdso_atomic_cmpxchg_32 and __vdso_atomic_barrier. (ld) [GLIBC_PRIVATE]: __rtld___vdso_read_tp, __rtld___vdso_atomic_cmpxchg_32, and __rtld___vdso_atomic_barrier. * sysdeps/unix/sysv/linux/m68k/coldfire/atomic-machine.h (atomic_compare_and_exchange_val_acq, atomic_full_barrier): Remove vDSO path for SHARED. * sysdeps/unix/sysv/linux/m68k/init-first.c: Remove file. * sysdeps/unix/sysv/linux/m68k/libc-m68k-vdso.c: Likewise. * sysdeps/unix/sysv/linux/m68k/m68k-helpers.S: Likewise. * sysdeps/unix/sysv/linux/m68k/m68k-vdso.c: Likewise. * sysdeps/unix/sysv/linux/m68k/m68k-vdso.h: Likewise. * sysdeps/unix/sysv/linux/m68k/m68k-helpers.c: New file.
