[PATCH 0 of 2] Paging support updates for XCP dom0
This is a cherry pick of two patches that add support for guest paged out
frames in the XCP 2.6.32 dom0 patch queue.
First patch propagates the ENOENT returned by the hypervisor in the case
of a paged out page, all the way up the call chain to the MMAPBATCH_V2
ioctl. The ioctl is mainly used to harvest those return values and retry.
The second patch adds retry loops to all backend grant

xenpaging fixes for kernel and hypervisor
Patrick,
there following patches fix xenpaging for me.
Granttable handling is incomplete. If a page is gone, a GNTST_eagain
should be returned to the caller to inidcate the hypercall has to be
retried after a while, until the page is available again.
Please review.

[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.)
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

RFC: [0/2] Remove netloop by lazy copying in netback
Hi Keir:
These two patches remove the need for netloop by performing the
copying in netback and only if it is necessary. The rationale
is that most packets will be processed without delay allowing
them to be freed without copying at all. So instead of copying
every packet destined to dom0 we''ll only copy those that linger
longer than a specified amount of time (currently 0.5s).
As it

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

This patch generally restricts itself to Xen-specific parts of the tree,
though it does make a few small changes elsewhere.
These patches include:

[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
