The DBDMA controller can not change its command stream while it's

doesn't actually indicate anything. It could just as well be in
WAIT while in RUN. And then it's legal to change commands.

When we offer a customer support service and a problem happens
in a customer's system, we try to understand the problem by
comparing what the customer reports with message logs of the
customer's system.
In this case, we often need to know when the problem happens.
But, currently, there is no timestamp in qemu's error messages.

In most places, we query these options with a null ID. This is
correct.
In some places, we instead query whatever options come first in the

have an ID, options are taken from that ID, and the ones specified
without ID are silently ignored.

Option usb is queried correctly, and the one without an ID wins,
regardless of option order.
Option accel is queried incorrectly, and which one wins depends on
option order and ID.
Affected options are accel (and its sugared forms -enable-kvm and
-no-kvm), kernel_irqchip, kvm_shadow_mem.
Additionally, option kernel_irqchip is normally on by default, except
it's off when no -machine options are given. Bug can't bite, because
kernel_irqchip is used only when KVM is enabled, KVM is off by
default, and enabling always creates -machine options. Downstreams
that enable KVM by default do get bitten, though.
Use qemu_get_machine_opts() to fix these bugs.

If defaults is true, and params has no ID, and options exist, we use
the first assignment. It sets opts to null if all options have an ID.
opts_parse() then returns null. qemu_opts_set_defaults() asserts the
value is non-null. It's the only caller that passes true for
defaults.
To reproduce, try "-M xenpv -machine id=foo" (yes, "id=foo" is silly,
but it shouldn't crash).
I believe the function attempts to do the following:
If options don't yet exist, create new options
Else, if defaults, modify the existing options
Else, if list->merge_lists, modify the existing options
Else, fail
A straightforward call of qemu_opts_create() does exactly that.

Commit 478032a93d908e59085c1ac56f10979942e7dc4f (target-openrisc:
Rename CPU subtypes) suffixed CPU sub-types with "-or32-cpu" but forgot
to update openrisc_cpu_class_by_name(), so that it was still looking for
the types without suffix.
Make target-openrisc running OK by adding the suffix to the model name.
This means it is no longer possible to use -cpu or1200-or32-cpu or
-cpu any-or32-cpu though.

With this we can generate armv7 insns even when the OS compiles for a
lower common denominator. The macros are arranged so that when we do
compile for a given ISA, all of the runtime checks for that ISA are
optimized away.

Expand the definition of "not present" to include "should not be present".
This means we can simplify the logic surrounding the generic tcg opcodes
for which the host backend ought not be providing definitions.

pci: Fold host_buses list into PCIHostState functionality
The host_buses list is an odd structure - a list of pointers to PCI root
buses existing in parallel to the normal qdev tree structure. This patch
removes it, instead putting the link pointers into the PCIHostState
structure, which have a 1:1 relationship to PCIHostBus structures anyway.

pci: Remove domain from PCIHostBus
There are now no users of the domain field of PCIHostBus, so remove it
from the structure, and as a parameter from the pci_host_bus_register()
function which sets it.
