+/* Full MCA functionality has the following Usecases from the guest side:
+ *
+ * Must have's:
+ * 1. Dom0 and DomU register machine check trap callback handlers
+ *    (already done via "set_trap_table" hypercall)
+ * 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

+ *
+ * Kexec under vanilla Linux allows a user to reboot the physical machine 
+ * into a new user-specified kernel. The Xen port extends this idea
+ * to allow rebooting of the machine from dom0. When kexec for dom0
+ * is used to reboot,  both the hypervisor and the domains get replaced
+ * with some other kernel. It is possible to kexec between vanilla
+ * Linux and Xen and back again. Xen to Xen works well too.
+ *
+ * The hypercall interface for kexec can be divided into three main
+ * types of hypercall operations:
+ *
+ * 1) Range information:
+ *    This is used by the dom0 kernel to ask the hypervisor about various 
+ *    address information. This information is needed to allow kexec-tools 
+ *    to fill in the ELF headers for /proc/vmcore properly.
+ *
+ * 2) Load and unload of images:
+ *    There are no big surprises here, the kexec binary from kexec-tools
+ *    runs in userspace in dom0. The tool loads/unloads data into the
+ *    dom0 kernel such as new kernel, initramfs and hypervisor. When
+ *    loaded the dom0 kernel performs a load hypercall operation, and
+ *    before releasing all page references the dom0 kernel calls unload.
+ *
+ * 3) Kexec operation:
+ *    This is used to start a previously loaded kernel.
