New Revision: 196188
URL: http://svn.freebsd.org/changeset/base/196188

Log:
  MFC r196185:
    Rather than replicating the maths from the kernel, use the
    value the kernel calculated directly as we already read it
    with struct vnet.  This will make kvm_vnet.c more resilent
    in case of possible kernel changes.
