I believe this series leaves a stray definition of INTERNAL_VSYSCALL_NCS
in aarch64:

/* List of system calls which are supported as vsyscalls.  */
# define HAVE_CLOCK_GETRES_VSYSCALL     1
# define HAVE_CLOCK_GETTIME_VSYSCALL    1
# define HAVE_GETTIMEOFDAY_VSYSCALL     1

# define INTERNAL_VSYSCALL_NCS(funcptr, err, nr, args...)       \

Otherwise it looks fine to me and I have reworked the ARM VDSO support
patch on top of it.
