This patch fixes the apm.c breakage in 2.5.29 by providing definitions
for num_possible_cpus() for UP and SMP. There were several patches
posted to fix it, but I think this is what the author intended. Rusty?

Patch against latest bitkeeper, compiles fine on UP and SMP. Don't
have an SMP machine to test it own.=20
