[PATCH 00/10] x86/paravirt: several cleanups
This series removes some no longer needed stuff from paravirt
infrastructure and puts large quantities of paravirt ops under a new
config option PARAVIRT_XXL which is selected by XEN_PV only.
A pvops kernel without XEN_PV being configured is about 2.5% smaller
with this series applied.

[PATCH 00/10] paravirt: make amount of paravirtualization configurable
Today paravirtualization is a all-or-nothing game: either a kernel is
compiled with no paravirtualization support at all, or it is supporting
paravirtualized environments like Xen pv-guests or lguest additionally
to some paravirtualized tuning for KVM, Hyperv, VMWare or Xen
HVM-guests.
As support of pv-guests requires quite intrusive pv-hooks (e.g. all
