Quick nit:
u16 mmu_slb_size = 64;
+EXPORT_SYMBOL_GPL(mmu_slb_size);
This value might change when doing a partition migration between a
POWER6 and a POWER7 so KVM might need to be extra careful...
It shouldn't be an issue.
The SLB size for the guest and the SLB size we project things on to on
the host are completely independent. So when we migrate, only the
guest information is transferred to the new host which then uses its
own SLB information to regenerate the shadow entries.
So everything's fine :-)
