So, I have two question now,
1. how to determine whether your kernel support SMP?
    Somebody taugh me that you can type "uname -r", but it seems not
2. I remember in 2.2.x, when I rebuild the kernel which support SMP, the
    argument will include -D__SMP__ , but this time, when I rebuild kernel
2.4.2-2 , it didn't appear.

Anyway, thanks for Vivek's answer.

This is just the label as defined by the entries in the top-level
Makefile, eg:

You can edit the extraversion value if you want to label your smp kernels
differently, but you don't have to.

You'll probably find you _have_ compiled an SMP kernel - see what
/proc/cpuinfo says, for example.

I am worthless. I struggle with the simple things. It seems so easy for 
everyone else. One armed blind people climb mountains and teenagers get
Ph.D's. I have trouble getting out of bed.
