Seems to work OK for native and Xen. I had to play a bit with the paravirt-sched-clock patch to deal with the VMI changes. Zach, can you check that it still works? Thanks, J

This is my current set of updates to Xen for 2.6.24. This is largely a bugfix set, and a couple of them are also relevent to 2.6.23. These are in the pre-x86 merge form; I'll update them once the merge goes into git. Quick overview: - remove some dead code in arch/i386/mm/init.c - clean up some duplicate includes - when sending an IPI, yield the vcpu if the destination doesn't have

Hi Linus, Here's a set of patches to update paravirt_ops and Xen for 2.6.24 A quick overview of the patchset: paravirt_ops: Remove the monolithic paravirt_ops structure, and replace it with smaller structures of related functions. Also, clean up the handling of lazy mode to make it easier to implement. x86/mm/init.c: remove a chunk of dead code Xen: - remove duplicate includes -

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

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-git3 + ff patches-2.6.21-git3-070501-1.tar.gz. Changes since the last posting: - reviews of xenbus (me), netfront (hch, rusty, herbert xu) and blockfront (hch), with most comments addressed. Netfront review revealed a couple of real bugs, and the code for all three is looking cleaner
