KVM: x86: do not pass poisoned hva to __kvm_set_memory_region __kvm_set_memory_region does not use the hva at all, so trying to catch use-after-delete is pointless and, worse, it fails access_ok now that we apply it to all memslots including private kernel ones. This fixes an AVIC regression. Fixes: 09d952c971a5 ("KVM: check userspace_addr for all memslots") Reported-by: Maxim Levitsky <mlevitsk@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
