This is odd. kvmppc_h_pr shouldn't be accessed when not in book3s_64_pr mode:

#ifdef CONFIG_KVM_BOOK3S_64_PR
                        if (kvmppc_h_pr(vcpu, cmd) == EMULATE_DONE) {
                                r = RESUME_GUEST;
                                break;
                        }
#endif

Could you please send me your .config?


Alex
