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
