We identify devices by their Open Firmware device paths. The encoding
of bus numbers is incorrect: idebus_get_fw_dev_path() formats them in
decimal, while SeaBIOS uses hexadecimal. With bus number > 9, SeaBIOS
will miss the bootindex (lucky case), or apply it to another device
(unlucky case).
Bug can't bite right now: ich9-ahci has six ports, and the sysbus-ahci
created by Calxeda Highbank has just one.
Fix it anyway, by changing %d to %x.
I couldn't find an Open Firmware spec covering this. For what it's

The SDM specifies (June 2014 Vol3 11.11.5):
On a hardware reset, the P6 and more recent processors clear the
valid flags in variable-range MTRRs and clear the E flag in the
IA32_MTRR_DEF_TYPE MSR to disable all MTRRs. All other bits in the
MTRRs are undefined.
We currently do none of that, so whatever MTRR settings you had prior
to reset is what you have after reset. Usually this doesn't matter
because KVM often ignores the guest mappings and uses write-back
anyway. However, if you have an assigned device and an IOMMU that
allows NoSnoop for that device, KVM defers to the guest memory
mappings which are now stale after reset. The result is that OVMF
rebooting on such a configuration takes a full minute to LZMA
decompress the firmware volume, a process that is nearly instant on
the initial boot.

The MTRR state in KVM currently runs completely independent of the
QEMU state in CPUX86State.mtrr_*. This means that on migration, the
target loses MTRR state from the source. Generally that's ok though
because KVM ignores it and maps everything as write-back anyway. The
exception to this rule is when we have an assigned device and an IOMMU
that doesn't promote NoSnoop transactions from that device to be cache
coherent. In that case KVM trusts the guest mapping of memory as
configured in the MTRR.
This patch updates kvm_get|put_msrs() so that we retrieve the actual
vCPU MTRR settings and therefore keep CPUX86State synchronized for
migration. kvm_put_msrs() is also used on vCPU reset and therefore
allows future modificaitons of MTRR state at reset to be realized.
Note that the entries array used by both functions was already
slightly undersized for holding every possible MSR, so this patch
increases it beyond the 28 new entries necessary for MTRR state.

This removes #ifdef s390 branch in qmp_inject_nmi so new s390's
nmi_monitor_handler() callback is going to be used for NMI.
Since nmi_monitor_handler()-calling code is platform independent,
CPUState::cpu_index is used instead of S390CPU::env.cpu_num.
There should not be any change in behaviour as both @cpu_index and
@cpu_num are global CPU numbers.
Note that s390_cpu_restart() already takes care of the specified cpu,
so we don't need to schedule via async_run_on_cpu().

This introduces an NMI (Non Maskable Interrupt) interface with
a single nmi_monitor_handler() method. A machine or a device can
implement it. This searches for an QOM object with this interface
and if it is implemented, calls it. The callback implements an action
required to cause debug crash dump on in-kernel debugger invocation.
The callback returns Error**.
This adds a nmi_monitor_handle() helper which walks through
all objects to find the interface. The interface method is called
for all found instances.
This adds support for it in qmp_inject_nmi(). Since no architecture
supports it at the moment, there is no change in behaviour.
