Seems like there was an additional bonus here.
It also made APIC_IO work. Just done a bunch of kernel compilations
with both APIC_IO and SMP_INVLTLB as well as all 4 CPU's running. Haven't
noticed any problems yet.
I've tried some patches from Steve lately, as well as some small changes
myself, so I did a fresh cvs checkout of the entire smp-current and it
looks like the fix above is all that is needed.
