[PATCH 0/4] paravirt clock series.
Respin of the paravirt clock patch series.
On the host side the kvm paravirt clock is made compatible with the
xen clock.
On the guest side some xen code has been factored out into a separate
source file shared by both kvm and xen clock implementations.
This time it should work ok for kvm smp guests ;)
cheers,
Gerd

[PATCH 0/5] paravirt clock source patches, #5
paravirt clock source patches, next round.
There is now a pvclock-abi.h file with the structs and some longish
comments in it and everybody is switched over to use the stuff in
there.
Some minor tweaks after super-fast review by Jeremy.
The queue is on top of the kvm git tree. The first two patches should
have no kvm dependencies and should apply to linus tree just fine.

[patch 00/20] paravirt_ops updates
Hi Andi,
Here's a repost of the paravirt_ops update series I posted the other day.
Since then, I found a few potential bugs with patching clobbering,
cleaned up and documented paravirt.h and the patching machinery.
Overview:
add-MAINTAINERS.patch
obvious
remove-CONFIG_DEBUG_PARAVIRT.patch
No longer meaningful or needed.

[patch 00/17] paravirt_ops updates
Hi Andi,
This series of patches updates paravirt_ops in various ways. Some of the
changes are plain cleanups and improvements, and some add some interfaces
necessary for Xen.
The brief overview:
add-MAINTAINERS.patch - obvious
remove-CONFIG_DEBUG_PARAVIRT.patch - no longer needed
paravirt-nop.patch - mark nop operations consistently
paravirt-pte-accessors.patch - operations to pack/unpack
