[patch] Initialize xen_vcpu0 before initialize irq_ops
...Sep 17 00:00:00 2001
From: Anthoine Bourgeois <anthoine.bourgeois@gmail.com>
Date: Wed, 23 Nov 2011 19:23:42 +0100
Subject: [PATCH] Initialize xen_vcpu0 before initialize irq_ops.
xen_vcpu is used by
xen_irq_ops.xen_{save_fl,restore_fl,irq_disable,irq_enable} and should
be initialized before xen_init_irq_ops that initialize the pv_irq_ops
with it. If not, a call to those functions could lead to a deference of
NULL pointer. This behaviour was find with a slow machine or qemu.

[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
