[PATCH] mark 3 variables as __initdata

The attached patch marks the following variables with __initdata:

        arch/i386/kernel/mpparse.c :: static unsigned int num_processors
        arch/i386/kernel/smpboot.c :: static int smp_b_stepping
        arch/i386/kernel/smpboot.c :: static int max_cpus

The data is static and only used by __init functions so can successfully
be jettisoned after boot.  Compiled and booted successfully on an SMP
machine.

I also set max_cpus to NR_CPUS instead of -1.  Besides being the
logically correct value and simplifying a loop elsewhere, this change
allows NR_CPUS to be set to various values other than the normal 32
which is growing in utility with the hotplug CPU changes now in
mainline.
