1) Move vdso data page up front and introduce enum vvar_pages, To pave the way for the subsequent support of TIME_NS, the support of TIME_NS will be issued in the later patch.
2) In arch_setup_additional_pages(), make Wait for the lock in the killable mode and return with EINTR if the task got killed while waiting.
