[PATCH 00/11] Xen arch portability patches
Hi. Recently the xen-ia64 community started to make efforts to merge
xen/ia64 Linux to upstream. The first step is to merge up domU portion.
This patchset is preliminary for xen/ia64 domU linux making the current
xen/x86 domU code more arch generic and adding missing definitions and
files.

[PATCH 00/12] Xen arch portability patches (take 4)
Hi Jeremy.
According to your suggestion, I recreated patches for Ingo's x86.git tree.
And this patch series includes Eddie's modification.
Please review and forward them. (or push back to respin.)

[PATCH 00 of 38] xen: add more Xen dom0 support
Hi Ingo,
Here''s the chunk of patches to add Xen Dom0 support (it''s probably
worth creating a new xen/dom0 topic branch for it).
A dom0 Xen domain is basically the same as a normal domU domain, but
it has extra privileges to directly access hardware. There are two
issues to deal with:
- translating to and from the domain''s pseudo-physical addresses and
real machine

[patch 00/20] XEN-paravirt: Xen guest implementation for paravirt_ops interface
This patch series implements the Linux Xen guest in terms of the
paravirt-ops interface. The features in implemented this patch series
are:
* domU only
* UP only (most code is SMP-safe, but there's no way to create a new vcpu)
* writable pagetables, with late pinning/early unpinning
(no shadow pagetable support)
* supports both PAE and non-PAE modes
* xen console
* virtual block

[PATCH 00/25] xen: Xen implementation for paravirt_ops
Hi Andi,
This series of patches implements the Xen paravirt-ops interface.
It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops
patches I posted.
This patch generally restricts itself to Xen-specific parts of the tree,
though it does make a few small changes elsewhere.
These patches include:
- some helper routines for allocating address space and walking pagetables
- Xen
