Hmm, I somehow can't trigger it here. And the thing is, vmw_balloon.c is
built only when CONFIG_VMWARE_BALLOON is set and that is not the case in
this config.

But still, I can see how this can still trigger because code is assuming
the presence of x86_hyper which those patches don't guarantee anymore. I
still haven't sorted out through my test builds here, will do so now and
check.

Thanks.
