We need a patch in the kernel for tpm
Hi!
Think I found a reference to the problem(s) I am seeing with
xen-tpmfront in my setup on the net:
https://patchwork.kernel.org/patch/9485637/
This patch has not been officially entered and it is not
included in the kernel provided in SIG virt either
Can we please get it in ?

[patch 00/32] xen: Xen implementation for paravirt_ops
Hi Andi,
This series of patches implements the Xen paravirt-ops interface.
It applies to 2.6.21 + 2.6.21-070428-1 + the patches I've posted over
the last couple of days.
Changes since the last posting:
- update per review comments
- comment each file
- comment barrier use
- use common cpu sibling setup
- fixed a few minor bugs, specifically a traceirq mismatch warning
- some

[patch 00/24] Xen-paravirt_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 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 hvc console (console=hvc0)

[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

[patch 00/28]xen: Xen implementation for paravirt_ops
Hi Andi,
This series of patches implements the Xen paravirt-ops interface. It
applies to 2.6.21-git13 + patches-2.6.21-git7-070507-1.tar.gz (I think
"unwinder" is the only patch which doesn't apply to git13, and the
sched-clock patches are the only ones which this series actually
needs).
Changes since the last posting:
- More netfront review and cleanup
- Added ability to
