- * Must have's:
- * 1. Dom0 and DomU register machine check trap callback handlers

- * 2. Dom0 registers machine check event callback handler
- * (doable via EVTCHNOP_bind_virq)
- * 3. Dom0 and DomU fetches machine check data
- * 4. Dom0 wants Xen to notify a DomU
- * 5. Dom0 gets DomU ID from physical address
- * 6. Dom0 wants Xen to kill DomU (already done for "xm destroy")
- *
- * Nice to have's:
- * 7. Dom0 wants Xen to deactivate a physical CPU
- * This is better done as separate task, physical CPU hotplugging,
- * and hypercall(s) should be sysctl's
- * 8. Page migration proposed from Xen NUMA work, where Dom0 can tell Xen to
- * move a DomU (or Dom0 itself) away from a malicious page
- * producing correctable errors.
- * 9. offlining physical page:
- * Xen free's and never re-uses a certain physical page.
- * 10. Testfacility: Allow Dom0 to write values into machine check MSR's
- * and tell Xen to trigger a machine check
