Well, the patch IS the fix for the build error.

paravirt.h just needs to be included if CONFIG_PARAVIRT is set. It isn't
enough to include it only if CONFIG_PARAVIRT_XXL is set.

The patch listed under "Fixes:" moved the halt related functions from the
CONFIG_PARAVIRT_XXL to the CONFIG_PARAVIRT umbrella, but missed to move
the #include of paravirt.h, too. This is what my patch is doing.
