[patch] stop passing in global variable as argument to cmos_init()

[Jes Sorensen <jes@xxxxxxx>]

Hi,

Looking through the ia64 code I came across this little gem.

At some point someone added a new argument to hw/pc.c:cmos_init() named
'smp_cpus', and then passed in the global variable 'smp_cpus' as the
argument. This propagated through to the ia64 code as well.

I checked, this isn't present in the upstream QEMU code, so lets kill
it in the KVM branch. One small step to get closer to upstream :-)

Cheers,
Jes

There is no reason to pass in global variable smp_cpus to cmos_init()
which then references it as a local variable of the same name 'smp_cpus'.
