After having installed a second processer I noticed that it's hard to
have both an smp 2.0.35 kernel and a non-smp 2.0.35 kernel when they're
modularized. Modules are installed in the same directory and non-smp
modules can be loaded in an smp kernel with horrible results.
The attached patch/diff fixes this problem by changing the 2.0.35
Makefile. It names a non-smp kernel just 2.0.35, but the smp-kernel is
called 2.0.35S. This results in modules that are installed in
/lib/modules/2.0.35S/ instead of /lib/modules/2.0.35/. This way both
kernels can coexist peacefully.
Go to the /usr/src/linux directory and apply the patch:
patch < Makefile.diff.
