This works differnetly than on sparc32 kernel (it works there).

I thought about the second condition from my previous post (elimnation 
of last cpu from the list of cpus). As far as I can see,  the max_cpus 
is always equal to NR_CPUS (is it true?). If so, the second condition is 
redudant (cpucount is always < NR_CPUS).
