Nicholas Piggin 120f738a46 spapr: implement nested-hv capability for the virtual hypervisor ... This implements the Nested KVM HV hcall API for spapr under TCG. The L2 is switched in when the H_ENTER_NESTED hcall is made, and the L1 is switched back in returned from the hcall when a HV exception is sent to the vhyp. Register state is copied in and out according to the nested KVM HV hcall API specification. The hdecr timer is started when the L2 is switched in, and it provides the HDEC / 0x980 return to L1. The MMU re-uses the bare metal radix 2-level page table walker by using the get_pate method to point the MMU to the nested partition table entry. MMU faults due to partition scope errors raise HV exceptions and accordingly are routed back to the L1. The MMU does not tag translations for the L1 (direct) vs L2 (nested) guests, so the TLB is flushed on any L1<->L2 transition (hcall entry and exit).
