Hello,

I'm running a Core2Duo on CURRENT, SMP kernel, but somehow the macro SMP
in machine/param.h 1.81 2006/01/09 line 68 is not defined, thus MAXCPU
is defined to 1. Any idea why?

It is defined in opt_global.h for a kernel build, but it is not defined in
userland. If you want to use MAXCPU in userland you should query the
appropriate sysctl (kern.smp.maxcpu) instead.

Thanks for the clarification!
