Yes, this is technically a no-op change if people are consistent
in using 'linux' vs 'hvm'. If they typo and use something else
then one part of the code would have treated it as HVM while another
would treat it as paravirt. This change just makes the driver
consistent in its inpretation, to always favour paravirt.

Yes, I was conservative when using STRPREFIX in my conversion.
I only change a few with static 2nd arg strings, because some of the
non-static ones were passing a non-static string, and a length
which was less than strlen() on the 2nd arg.
