If this is the last patch in the series then something
else in the series is appearing too early in it.
The patchset should put in all the handling for WHPX
first, and then as the last thing it does, enable it so
that you can configure/enable it. There shouldn't be
a point in the middle of the commit series where you
can enable and build it but it's still missing pieces.
