/* This file describes the Kexec / Kdump hypercall interface for Xen.
 *
 * 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.

/* Full MCA functionality has the following Usecases from the guest side:

 * 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

 * Macros to make the correct C datatypes for a new kind of ring.
 * 
 * To make a new ring datatype, you need to have two message structures,
 * let's say request_t, and response_t already defined.
 *
 * In a header where you want the ring datatype declared, you then do:
 *
 *     DEFINE_RING_TYPES(mytag, request_t, response_t);
 *
 * These expand out to give you a set of types, as you can see below.
 * The most important of these are:
 * 
 *     mytag_sring_t      - The shared ring.
 *     mytag_front_ring_t - The 'front' half of the ring.
 *     mytag_back_ring_t  - The 'back' half of the ring.
 *
 * To initialize a ring in your code you need to know the location and size
 * of the shared memory area (PAGE_SIZE, for instance). To initialise
 * the front half:
 *
 *     mytag_front_ring_t front_ring;
 *     SHARED_RING_INIT((mytag_sring_t *)shared_page);
 *     FRONT_RING_INIT(&front_ring, (mytag_sring_t *)shared_page, PAGE_SIZE);
 *
 * Initializing the back follows similarly (note that only the front
 * initializes the shared ring):
 *
 *     mytag_back_ring_t back_ring;
 *     BACK_RING_INIT(&back_ring, (mytag_sring_t *)shared_page, PAGE_SIZE);
