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?

# error SMP not defined
#endif
> make smp
cc -O2 -pipe -march=pentiumpro smp.c -o smp
smp.c:5:3: error: #error SMP not defined
*** Error code 1
> cat maxcpu.c
#include <sys/param.h>
#include <stdio.h>
int main(void)
{
return (MAXCPU);
}
> ./maxcpu; echo $?
1
Any idea?
