a) have smp=1 enabled by default in the makefile
and
b) function on a single processor system, when compiled
with smp enabled
do we gain anything (speed/stability/etc) by removing the smp
define if we run the kernel on a single processor system?
i.e. is it a function of the correct init functions, or are there
smp specific optimizations/changes that will negativly impact
a single cpu system? what's the developers take on this?
