pc: Ensure non-zero CPU ref count after attaching to ICC bus
Setting the parent bus of a device increases its ref count, which we
ultimately want to level out. However it is only safe to do so after the
last reference to the device in local code, as qom-set or similar operations
might decrease the ref count.
Therefore move the object_unref() from pc_new_cpu() into its callers.
The APIC operations on the last CPU in pc_cpus_init() are still potentially
insecure, but that is beyond the scope of this code movement.

xen/MSI-X: limit error messages
Limit error messages resulting from bad guest behavior to avoid allowing
the guest to cause the control domain's disk to fill.
The first message in pci_msix_write() can simply be deleted, as this
is indeed bad guest behavior, but such out of bounds writes don't
really need to be logged.
The second one is more problematic, as there guest behavior may only
appear to be wrong: For one, the old logic didn't take the mask-all bit
into account. And then this shouldn't depend on host device state (i.e.
the host may have masked the entry without the guest having done so).
Plus these writes shouldn't be dropped even when an entry is unmasked.
Instead, if they can't be made take effect right away, they should take
effect on the next unmasking or enabling operation - the specification
explicitly describes such caching behavior. Until we can validly drop
the message (implementing such caching/latching behavior), issue the
message just once per MSI-X table entry.
Note that the log message in pci_msix_read() similar to the one being
removed here is not an issue: "addr" being of unsigned type, and the
maximum size of the MSI-X table being 32k, entry_nr simply can't be
negative and hence the conditonal guarding issuing of the message will
never be true.

The ARM GICv2m widget is a little device that handles MSI interrupt
writes to a trigger register and ties them to a range of interrupt lines
wires to the GIC. It has a few status/id registers and the interrupt wires,
and that's about it.
A board instantiates the device by setting the base SPI number and
number SPIs for the frame. The base-spi parameter is indexed in the SPI
number space only, so base-spi == 0, means IRQ number 32. When a device
(the PCI host controller) writes to the trigger register, the payload is
the GIC IRQ number, so we have to subtract 32 from that and then index
into our frame of SPIs.
When instantiating a GICv2m device, tell PCI that we have instantiated
something that can deal with MSIs. We rely on the board actually wiring
up the GICv2m to the PCI host controller.

monitor: Use trad. command interface for HMP pcie_aer_inject_error
All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one. Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.
pcie_aer_inject_error's implementation is split into the
hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The
former is a peculiar crossbreed between HMP and QMP handler. On
success, it works like a QMP handler: store QDict through ret_data
parameter, return 0. Printing the QDict is left to
pcie_aer_inject_error_print(). On failure, it works more like an HMP
handler: print error to monitor, return negative number.
To convert to the traditional interface, turn
pcie_aer_inject_error_print() into a command handler wrapping around
hmp_pcie_aer_inject_error(). By convention, this command handler
should be called hmp_pcie_aer_inject_error(), so rename the existing
hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

monitor: Drop broken, unused asynchronous command interface
The asynchronous monitor command interface goes back to commit 940cc30
(Jan 2010). Added a third case to command execution. The hope back
then according to the commit message was that all commands get
converted to the asynchronous interface, killing off the other two
cases. Didn't happen.
The initial asynchronous commands balloon and info balloon were
converted back to synchronous long ago (commit 96637bc and d72f32),
with commit messages calling the asynchronous interface "not fully
working" and "deprecated". The only other user went away in commit 3b5704b.
New code generally uses synchronous commands and asynchronous events.
What exactly is still "not fully working" with asynchronous commands?
Well, here's a bug that defeats actual asynchronous use pretty
reliably: the reply's ID is wrong (and has always been wrong) unless
you use the command synchronously! To reproduce, we need an
asynchronous command, so we have to go back before commit 3b5704b.

i386/pc_q35: don't insist on board FDC if there's no default floppy
The "no_floppy = 1" machine class setting causes "default_floppy" in

drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no
default floppy drive will be created for the virtual machine. In that
case, board code should also not insist on the creation of the
board-default FDC.
The board-default FDC will still be created if the user requests a floppy
drive with "-drive if=floppy".
Additionally, separate FDCs can be specified manually with "-device

At the moment both callers pass constant create_fdctrl=true (hence no

Assuming a board passes create_fdctrl=false, "floppy" will be NULL on

virtio: device_plugged() can fail
This patch passes error pointer to transport specific device_plugged()

check the number of virtqueues against the transport limitation.
