The series adds support for the new hypercall ABI which should be provided by Xen 4.3. Images are loaded into Xen directly with no kernel involvement. Do not apply until the hypervisor side patches are applied to Xen. Patch 1 is unrelated but kexec wouldn''t work for me without it. Not sure why I had problems, perhaps a toolstack specific issue? Patch 2 makes libxc 4.3 mandatory for Xen support. Patch 3-4 removes a use of /proc/iomem in favour of libxc. Patch 5 adds the support for loading, unloading, and exec''ing an image in Xen. This series explicitly drops support for older version of libxc/Xen as supporting kexec on these hypervisors requires kernel support that will never be available upstream. Changes since v1: - Patch from Don Sultz: use libxc for vmcoreinfo. - Use xc_get_max_cpus() to get number of PCPUs. - Enable unload and exec of images. David

Please fix that and repost. Xen patches applies to latest Xen unstable tree with some warnings. I think it is worth update those patches too. Daniel
