Here are some refactorings to prepare for an SVM implementation of KVM_SET_NESTED_STATE. It's a prerequisite for that to eliminate exit_required, moving exceptions to svm_check_nested_events. However: - I might work on that soon, because it's needed to handle RSM when the L1 hypervisor wants to get it from #UD rather than the specific RSM intercept - this should be enough to get a quick prototype, that I need in order to debug a particularly crazy bug and figure out its reproducibility. So, I am getting these patches out of my todo list for now. Thanks, Paolo Paolo Bonzini (7): KVM: SVM: move map argument out of enter_svm_guest_mode KVM: SVM: extract load_nested_vmcb_control KVM: SVM: extract preparation of VMCB for nested run KVM: SVM: save all control fields in svm->nested KVM: nSVM: remove HF_VINTR_MASK KVM: nSVM: do not reload pause filter fields from VMCB KVM: SVM: introduce data structures for nested virt state arch/x86/include/asm/kvm_host.h | 1 - arch/x86/include/uapi/asm/kvm.h | 26 +++++++- arch/x86/kvm/svm/nested.c | 115 +++++++++++++++++--------------- arch/x86/kvm/svm/svm.c | 11 ++- arch/x86/kvm/svm/svm.h | 28 +++++--- 5 files changed, 116 insertions(+), 65 deletions(-)
