[Xen-devel] [PATCH 06/10] x86/paravirt: introduce new config option PARAVIRT_XXL

[Juergen Gross <jgross@xxxxxxxx>]

A large amount of paravirt ops is used by Xen PV guests only. Add a new
config option PARAVIRT_XXL which is selected by XEN_PV. Later we can
put the Xen PV only paravirt ops under the PARACVIRT_XXL umbrella.
