KVM: x86: hyperv: valid_bank_mask should be 'u64'
This probably doesn't matter much (KVM_MAX_VCPUS is much lower nowadays) but valid_bank_mask is really u64 and not unsigned long. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Reviewed-by: Roman Kagan <rkagan@virtuozzo.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
