At the moment that looks like I'll be making changes to Xen itself, as well as the kernel, so there will likely be a requirement to track fairly up-to-date versions of xen-unstable for a while * I will be upstreaming pieces of dom0 support as they become ready and look acceptable for upstreaming. The goal is to start shrinking the side of the out-of-tree patches as core kernel support increases. This is going to be an incremental process, but it will work much better than trying to shove everything in at once. The smaller (and less intrusive) the out-of-tree patchset becomes, the easier it is for distros to include it in their own patchset. For now I've backed off putting anything much into the current merge window, or even the next, in favour of getting the tree into good shape for Xen users and working out what needs to happen to get a solid set of upstreamable patches.
