Here's another minor cleanup. Looks like wall_time_nsec is being set
twice.

vsyscall_gtod_data.wall_to_monotonic = wall_to_monotonic;
write_sequnlock_irqrestore(&vsyscall_gtod_data.lock, flags);
}
Also, is there a reason why with the new __vdso_gettimeofday
implementation, the old do_vgettimeofday has not been removed?
thanks
