Do you mean moving run->exit_reason = ... and vcpu->arch.hcall_needed = ... into arch/powerpc/kvm/book3s_emulate.c ? If yes, then no you did not miss :) as I have not sent. I will send the new patch with other patches in the patch-set. -Bharat > > > Alex > > -- > To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body > of a message to majord...@vger.kernel.org More majordomo info at > http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
