note about compiling SMP kernels

Just a quick note for those of you who are trying to compile up a
kernel for an SMP powermac: make sure that you are not using an old
arch/ppc/kernel/ppc_defs.h file from a UP compile.  For instance, my
rsync trees have a version of this file in them which is suitable for
a UP compile.

So, before compiling for SMP for the first time, do a make clean in
the tree first, even if the tree has no object files in it.
