From: Nicu?or C??u <ncitu at bitdefender.com> This is needed for the KVMI_VCPU_SET_REGISTERS command, without clearing the pending exception. The KVMI_VCPU_SET_REGISTERS commmand allows the introspectiont tool to override the kvm_regs structure of a specific vCPU. But in most cases this is used to increment the program counter.

This patch series is based on the VM introspection patches (https://lore.kernel.org/kvm/20200721210922.7646-1-alazar at bitdefender.com/), extending the introspection API with EPT Views and Virtualization Exceptions (#VE) support. The purpose of this series is to get an initial feedback and to see if we are on the right track, especially because the changes made to add the EPT views are not small
