With HV KVM, the guest's hash page table (HPT) is managed by the kernel and not directly accessible to QEMU. This means that spapr->htab is NULL and normally env->external_htab would also be NULL for each cpu. However, that would cause ppc_hash64_load_hpte*() to do the wrong thing in the few cases where QEMU does need to load entries from the in-kernel HPT. Specifically, seeing external_htab is NULL, they would look for an HPT within the guest's address space instead. To stop that we have an ugly hack in the pseries machine type code to set external htab to (void *)1 instead. This patch removes that hack by having ppc_hash64_load_hpte*() explicitly check kvmppc_kern_htab instead, which makes more sense.
