[techtalk] insmod, RH62 SMP

[Eito Katagiri]

Hi,

How did you build your module? I think that you need to
define "SMP" to compile a module for SMP-enabled kernel.
If you look at some source, there are "#ifdef"s for SMP.
I believe that you can define it as compiler option like
"gcc -DSMP foo.c"

HTH,
