vfio: unplug failover primary device before migration
As usual block all vfio-pci devices from being migrated, but make an
exception for failover primary devices. This is achieved by setting
unmigratable to 0 but also add a migration blocker for all vfio-pci
devices except failover primary devices. These will be unplugged before
migration happens by the migration handler of the corresponding
virtio-net standby device.

net/virtio: add failover support
This patch adds support to handle failover device pairs of a virtio-net
device and a (vfio-)pci device, where the virtio-net acts as the standby
device and the (vfio-)pci device as the primary.
The general idea is that we have a pair of devices, a (vfio-)pci and a
emulated (virtio-net) device. Before migration the vfio device is
unplugged and data flows to the emulated device, on the target side
another (vfio-)pci device is plugged in to take over the data-path. In the
guest the net_failover module will pair net devices with the same MAC
address.
To achieve this we need:
1. Provide a callback function for the should_be_hidden DeviceListener.
It is called when the primary device is plugged in. Evaluate the QOpt
passed in to check if it is the matching primary device. It returns
if the device should be hidden or not.
When it should be hidden it stores the device options in the VirtioNet
struct and the device is added once the VIRTIO_NET_F_STANDBY feature is
negotiated during virtio feature negotiation.
If the virtio-net devices are not realized at the time the (vfio-)pci
devices are realized, we need to connect the devices later. This way
we make sure primary and standby devices can be specified in any
order.
2. Register a callback for migration status notifier. When called it
will unplug its primary device before the migration happens.
3. Register a callback for the migration code that checks if a device
needs to be unplugged from the guest.

migration: add new migration state wait-unplug
This patch adds a new migration state called wait-unplug. It is entered
after the SETUP state if failover devices are present. It will transition
into ACTIVE once all devices were succesfully unplugged from the guest.
So if a guest doesn't respond or takes long to honor the unplug request
the user will see the migration state 'wait-unplug'.
In the migration thread we query failover devices if they're are still
pending the guest unplug. When all are unplugged the migration
continues. If one device won't unplug migration will stay in wait_unplug
state.

qdev/qbus: add hidden device support
This adds support for hiding a device to the qbus and qdev APIs. The
first user of this will be the virtio-net failover feature but the API
introduced with this patch could be used to implement other features as
well, for example hiding pci devices when a pci bus is powered off.
qdev_device_add() is modified to check for a failover_pair_id
argument in the option string. A DeviceListener callback
should_be_hidden() is added. It can be used by a standby device to
inform qdev that this device should not be added now. The standby device
handler can store the device options to plug the device in at a later
point in time.
One reason for hiding the device is that we don't want to expose both
devices to the guest kernel until the respective virtio feature bit
VIRTIO_NET_F_STANDBY was negotiated and we know that the devices will be
handled correctly by the guest.
More information on the kernel feature this is using:
https://www.kernel.org/doc/html/latest/networking/net_failover.html
An example where the primary device is a vfio-pci device and the standby
device is a virtio-net device:
A device is hidden when it has an "failover_pair_id" option, e.g.
-device virtio-net-pci,...,failover=on,...
-device vfio-pci,...,failover_pair_id=net1,...

qapi: Fix doc comment checking for commands and events
When a command's 'data' is an object, its doc comment describes the
arguments defined there. When 'data' names a type, the doc comment
does not describe arguments. Instead, the doc generator inserts a
pointer to the named type.
An event's doc comment works the same.
We don't actually check doc comments for commands and events.
Instead, QAPISchema._def_command() forwards the doc comment to the
implicit argument type, where it gets checked. Works because the
check only cares for the implicit argument type's members.
Not only is this needlessly hard to understand, it actually falls
apart in two cases:
* When 'data' is empty, there is nothing to forward to, and the doc
comment remains unchecked. Demonstrated by test doc-bad-event-arg.
* When 'data' names a type, we can't forward, as the type has its own
doc comment. The command or event's doc comment remains unchecked.
Demonstrated by test doc-bad-boxed-command-arg.
The forwarding goes back to commit
069fb5b250 "qapi: Prepare for
requiring more complete documentation", put to use in commit
816a57cd6e "qapi: Fix detection of bogus member documentation". That
fix was incomplete.

comments, and drop the forwarding of doc comments to implicit argument
types.

qapi: Clean up doc comment checking for implicit union base
An object type's doc comment describes the type's members, less the
ones defined in a named base type. Cases:
* Struct: the members are defined in 'data' and inherited from 'base'.
Since the base type cannot be implicit, the doc comment describes
just 'data'.
* Simple union: the only member is the implicit tag member @type, and
the doc comment describes it.
* Flat union with implicit base type: the members are defined in
'base', and the doc comment describes it.
* Flat union with named base type: the members are inherited from
'base'. The doc comment describes no members.
Before we can check a doc comment with .check_doc(), we need
.connect_doc() connect each of its "argument sections" to the member
it documents.
For structs and simple unions, this is straightforward: the members in
question are in .local_members, and .connect_doc() connects them.
For flat unions with a named base type, it's trivial: .local_members
is empty, and .connect_doc() does nothing.
For flat unions with an implicit base type, it's tricky. We have
QAPISchema._make_implicit_object_type() forward the union's doc
comment to the implicit base type, so that the base type's
.connect_doc() connects the members. The union's .connect_doc() does
nothing, as .local_members is empty.
Dirt effect: we check the doc comment twice, once for the union type,
and once for the implicit base type.
This is needlessly brittle and hard to understand. Clean up as
follows. Make the union's .connect_doc() connect an implicit base's
members itself. Do not forward the union's doc comment to its
implicit base type.
Requires extending .connect_doc() so it can work with a doc comment
other than self.doc. Add an optional argument for that.

tests/boot_linux_console: Add a test for the Raspberry Pi 2
Similar to the x86_64/pc test, it boots a Linux kernel on a raspi2

The kernel image and DeviceTree blob are built by the Raspbian
project (based on Debian):
https://www.raspbian.org/RaspbianImages
as recommended by the Raspberry Pi project:
https://www.raspberrypi.org/downloads/raspbian/
If ARM is a target being built, "make check-acceptance" will
automatically include this test by the use of the "arch:arm" tags.
Alternatively, this test can be run using:
$ avocado run -t arch:arm tests/acceptance

Merge remote-tracking branch 'remotes/palmer/tags/riscv-for-master-4.2-sf2' into staging
RISC-V Patches for the 4.2 Soft Freeze, Part 2
This patch set contains a handful of small fixes for RISC-V targets that
I'd like to target for the 4.2 soft freeze. They include:
* A fix to allow the debugger to access the state of all privilege
modes, as opposed to just the currently executing one.
* A pair of cleanups to implement cpu_do_transaction_failed.
* Fixes to the device tree.
* The addition of various memory regions to make the sifive_u machine
more closely match the HiFive Unleashed board.
* Fixes to our GDB interface to allow CSRs to be accessed.
* A fix to a memory leak pointed out by coverity.
* A fix that prevents PMP checks from firing incorrectly.
This passes "make chcek" and boots Open Embedded for me.

hw/m68k: add VIA support
Inside the 680x0 Macintosh, VIA (Versatile Interface Adapter) is used
to interface the keyboard, Mouse, and real-time clock. It also provides
control line for the floppy disk driver, video interface, sound circuitry
and serial interface.
This implementation is based on the MOS6522 object.

esp: add pseudo-DMA as used by Macintosh
There is no DMA in Quadra 800, so the CPU reads/writes the data from the
PDMA register (offset 0x100, ESP_PDMA in hw/m68k/q800.c) and copies them
to/from the memory.
There is a nice assembly loop in the kernel to do that, see
linux/drivers/scsi/mac_esp.c:MAC_ESP_PDMA_LOOP().
The start of the transfer is triggered by the DREQ interrupt (see linux
mac_esp_send_pdma_cmd()), the CPU polls on the IRQ flag to start the
transfer after a SCSI command has been sent (in Quadra 800 it goes
through the VIA2, the via2-irq line and the vIFR register)
The Macintosh hardware includes hardware handshaking to prevent the CPU
from reading invalid data or writing data faster than the peripheral
device can accept it.
This is the "blind mode", and from the doc:
"Approximate maximum SCSI transfer rates within a blocks are 1.4 MB per
second for blind transfers in the Macintosh II"

Benchmarking over a fixed data size avoids the loop running any system
