From: ?tefan ?icleru <ssicleru at bitdefender.com> Add a view mask for kvm_mmu_zap_all() in order to allow zapping shadow pages for specific EPT views. This is required when an introspected VM is unhooked. In that case, shadow pages that belong to non-default views will be zapped.

The host needs to zap its shadow entries before performing an inflate operation to avoid the guest from using stale ones. So add an ioctl to interface with kvm_mmu_zap_all().

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
