Anthony Liguori b95fdc0e99 This is a set of patches dealing with kdump support for s390x/kvm. 
kdump on s390x uses subcode 1 of diagnose 0x308 to put the hardware
 in a defined state. This is different from a full reset, since it
 does not touch all CPU registers.
 These patches define the cpu resets, the subsystem reset a load
 function and also wires up the "nmi" command to issue a RESTART
 interrupt as defined in the z/Architecture principles of operation.
 
 This allows recent guest kernels with properly setup userspace
 to trigger kdump:
 - via guest crash
 - via nmi from the host
