Nicholas Piggin 22f7ff0dea KVM: PPC: Book3S HV Nested: Fix nested HFSCR being clobbered with multiple vCPUs ... The L0 is storing HFSCR requested by the L1 for the L2 in struct kvm_nested_guest when the L1 requests a vCPU enter L2. kvm_nested_guest is not a per-vCPU structure. Hilarity ensues. Fix it by moving the nested hfscr into the vCPU structure together with the other per-vCPU nested fields.
