On iSeries the Hypervisor has already inserted some ptes for us, and we simply have to detect that and bolt them. iSeries_hpte_bolt_or_insert() implements that logic. For the case of a non-existing pte we just call iSeries_hpte_insert(). This appears to work, although it's not entirely equivalent to the old code in iSeries_make_pte() which panicked if we got a secondary slot. Not sure if that's important. Finally we call iSeries_hpte_bolt_or_insert() from create_pte_mapping(), which is called from htab_initialize() for each lmb region.
