This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block device (blockfront) (Netfront needs a bit of updating, and will be in a separate patch later.) The patch series is in two parts: 1-11: cleanups to the core kernel, either to fix outright problems, or to add appropriate hooks for Xen 12-20: the Xen guest implementation itself I've tried to make each patch as self-explanatory as possible. The series is based on 2.6.20-rc4-mm1. Thanks, J --
