What Milton said. It's a high availability feature.
We can register volatile and persistent SLBs with PHYP. PHYP will
invalidate volatile entries and replace persistent entries if it sees a
problem with them.
Here I've only registered the 3 persistent (bolted) SLBs, as the
volatile SLBs can be handled with SLB faults in the kernel.
