2007-04-11 Thread Gregory Haskins
Hi All, Attached are the first three patches in my queue. The first two you are likely familiar with at this point (though I have made some more of the requested changes to 02-irqdevice.patch). The last item (03-preemptible-cpu.patch) adds an implementation to the previously unused kvm_vcp
