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
