Hi, Here is next bundle of fixes for crash Xen support: - xen: Fix page tables caching issues, - xen: Use init_tss array or per_cpu__init_tss, - xen: Use per_cpu__crash_notes or crash_notes array, - xen: Try hard to get max_cpus value, - xen: Use cpu_present_map instead of cpu_online_map. All patches were tested with Xen versions up to 4.2. Daniel
