[patch 00/34] Xen-pv_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 and SMP guest support (NEW!) * dynamic ticks (NEW!) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes (non-PAE may be broken at the moment) * xen hvc console
