[PATCH 0 of 4] Prune outdated/impossible preprocessor symbols, and update VIOAPIC emulation
Patch 1 removes CONFIG_SMP
Patch 2 removes separate smp_{,r,w}mb()s as a result of patch 1
Patch 4 removes __ia64__ defines from the x86 arch tree
Patch 3 is related to patch 4 and changes the VIOAPIC to emulate
version 0x20 as a performance gain. It preceeds Patch 4 so as to be
more clear about the functional change.

[patch 00/34] Xen-pv_ops: Xen guest implementation for paravirt_ops interface
Hi Andi,
This patch series implements the Linux Xen guest as a paravirt_ops
backend. The features in implemented this patch series are:
* domU only
* UP and SMP guest support (NEW!)
* dynamic ticks (NEW!)
* writable pagetables, with late pinning/early unpinning
(no shadow pagetable support)
* supports both PAE and non-PAE modes
(non-PAE may be broken at the moment)
* xen hvc console

[PATCH v4 00/25] xen: ARMv7 with virtualization extensions
Hello everyone,
this is the fourth version of the patch series that introduces ARMv7
with virtualization extensions support in Xen.
The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile
Express simulator.
See the following announce email for more informations about what we
are trying to achieve, as well as the original git history:
