[PATCH] init/main.c: make setup_max_cpus static for !SMP

[H Hartley Sweeten <hartleys@visionengravers.com>]

init/main.c: make setup_max_cpus static for !SMP

The only in tree external users of the symbol setup_max_cpus are in
arch/x86/. The files ./kernel/alternative.c, ./kernel/visws_quirks.c, and
./mm/kmemcheck/kmemcheck.c are all guarded by CONFIG_SMP
being defined. For this case the symbol is an unsigned int and
declared as an extern in include/linux/smp.h.

When CONFIG_SMP is not defined the symbol setup_max_cpus is
a constant value that is only used in init/main.c.  Make the symbol
static for this case.
