kswapd and SMP still broke on 2.2.0-pre9

[Troy Benjegerdes]

kswapd is still dieing on boot with SMP enabled (and this time the second
processor is actually active)

Does this indicate something is wrong with SMP and the MM code, or that
some PPC-specific part needs fixing? I've tried to keep up on
linux-kernel, but it's a little overwhelming ;)
