Alex,
here is the adopted series.
- Patch 1 is new, to make patch2 look better
- Patch 2 was adopted to move everything into misc helper
please note: I did not wire up the tcg diag handler for known reasons
This should be trivial to implement
- Patch 5 was also slightly adopted to make the full reset identical to
the previous state (The old patch changed the order of some reset steps)
- Patch 6 was adopted to also go into misc_helper
- Patch 3,4,7 are unchanged
All patches compile- and checkpatch tested. kdump functionality, reboot,
signal quiesce, cpu online/offline tested on s390x/kvm. Basic run of s390x
emulation on i386 also tested.
Please ACK the series.
Anthony, can you pull afterwards?

s390: wire up nmi command to raise a RESTART interrupt on S390 (2013-08-30
14:16:48 +0200)
----------------------------------------------------------------
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
----------------------------------------------------------------
Christian Borntraeger (5):
s390x/kvm: Fix switch/case indentation for handle_diag
s390: provide I/O subsystem reset
s390: provide a cpu load normal function
s390/cpu: split CPU reset into architectured functions
s390: Implement load normal reset
Eugene (jno) Dvurechenski (2):
s390/kvm: basic implementation of diagnose 308 subcode 6
s390: wire up nmi command to raise a RESTART interrupt on S390
