Merge remote-tracking branch 'borntraeger/tags/kdump' into staging
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
