Erm, that's not what that is there for. It is there because the clock is not
safe for SMP use. I.e., we only use that timecounter in a UP machine. We
don't call cpu_initclocks() multiple times. However, on the alpha we always
call hardclock() (and thus tc_windup()) on the boot CPU, thus it _might_ be
safe for us to use this timecounter on SMP systems. In any case,
cpu_initclocks() is only called once, so the 'once' variable is bogus. Please
revert that part for now.
