Rather than retaining io_mem_read/write as simple wrappers around
the memory_region_dispatch_read/write functions, make the latter
public and change all the callers to use them, since we need to
touch all the callsites anyway to add MemTxAttrs and MemTxResult
support. Delete io_mem_read and io_mem_write entirely.
(All the callers currently pass MEMTXATTRS_UNSPECIFIED
and convert the return value back to bool or ignore it.)

Current QEMU crashes when specifying an illegal model with the
"-net nic,model=xxx" option, e.g.:
$ qemu-system-x86_64 -net nic,model=n/a
qemu-system-x86_64: Unsupported NIC model: n/a
Program received signal SIGSEGV, Segmentation fault.
The gdb backtrace looks like this:

The problem is that pci_nic_init_nofail() does not check whether the err

to error_report_err(). Fix it by correctly checking the err parameter.

memory_region_allocate_system_memory
Commit 0b183fc871:"memory: move mem_path handling to

memory_region_init_ram_from_file. Also it moved mem-path handling a step

Therefore for any board that uses memory_region_init_ram directly,

After qemu_iovec_destroy, the QEMUIOVector's size is zeroed and
the zero size ultimately is used to compute virtqueue_push's len
argument. Therefore, reads from virtio-blk devices did not
migrate their results correctly. (Writes were okay).
Save the size in virtio_blk_handle_request, and use it when the request
is completed.

Since the BSP bit is writable on real hardware, during reset all the CPUs which
were not chosen to be the BSP should have their BSP bit cleared. This fix is
required for KVM to work correctly when it changes the BSP bit.
An additional fix is required for QEMU tcg to allow software to change the BSP
bit.

Device models aren't supposed to go on fishing expeditions for
backends. They should expose suitable properties for the user to set.
For onboard devices, board code sets them.
A number of sysbus devices pick up block backends in their init() /
instance_init() methods with drive_get_next() instead: sl-nand,
milkymist-memcard, pl181, generic-sdhci.
Likewise, a number of sysbus devices pick up character backends in
their init() / realize() methods with qemu_char_get_next_serial():
cadence_uart, digic-uart, etraxfs,serial, lm32-juart, lm32-uart,
milkymist-uart, pl011, stm32f2xx-usart, xlnx.xps-uartlite.
All these mistakes are already marked FIXME. See the commit that
added these FIXMEs for a more detailed explanation of what's wrong.
Fortunately, only machines ppce500 and pseries-* support -device with
sysbus devices, and none of the devices above is supported with these
machines.
Set cannot_instantiate_with_device_add_yet to preserve our luck.

it before this mistake becomes ABI, and we have to support command

NICs defined with -net nic are for board initialization to wire up.
Board code examines nd_table[] to find them, and creates devices with
their qdev NIC properties set accordingly.
Except "allwinner-a10" goes on a fishing expedition for NIC
configuration instead of exposing the usual NIC properties for board
code to set: it uses nd_table[0] in its instance_init() method.
Picking up the first -net nic option's configuration that way works
when the device is created by board code. But it's inappropriate for
-device and device_add. Not only is it inconsistent with how the
other block device models work (they get their configuration from
properties "mac", "vlan", "netdev"), it breaks when nd_table[0] has
been picked up by the board or a previous -device / device_add
already.
Example:
$ qemu-system-arm -S -M cubieboard -device allwinner-a10
qemu-system-arm: -device allwinner-a10: Property 'allwinner-emac.netdev' can't take value 'hub0port0', it's in use
Aborted (core dumped)
It also breaks in other entertaining ways:
$ qemu-system-arm -M highbank -device allwinner-a10
qemu-system-arm: -device allwinner-a10: Unsupported NIC model: xgmac
$ qemu-system-arm -M highbank -net nic,model=allwinner-emac -device allwinner-a10

Character devices defined with -serial and -parallel are for board
initialization to wire up. Board code examines serial_hds[] and
parallel_hds[] to find them, and creates devices with their qdev
chardev properties set accordingly.
Except a few devices go on a fishing expedition for a suitable backend
instead of exposing a chardev property for board code to set: they use
serial_hds[] (often via qemu_char_get_next_serial()) or parallel_hds[]
in their realize() or init() method to connect to a backend.
Picking up backends that way works when the devices are created by
board code. But it's inappropriate for -device or device_add. Not
only is it inconsistent with how the other characrer device models
work (they connect to a backend explicitly identified by a "chardev"
property), it breaks when the backend has been picked up by the board
or a previous -device / device_add already.
Example:
$ qemu-system-ppc64 -M bamboo -S -device i82378 -device pc87312 -device pc87312
qemu-system-ppc64: -device pc87312: Property 'isa-parallel.chardev' can't take value 'parallel0', it's in use

Patch queue for 2.3 ppc - 2015-03-25
Just a few bug fixes before 2.3 gets released:
- pseries: Firmware update, bugfixes
- remove POWER5+ v0.0 that we incorrectly introduced in 2.3
- Fix -machine usb=no
- Fix -boot once=foo in pseries
- Add NULL pointer check in pseries machine init

Capture the explicit setting of "usb=no" into a separate bool, and
use it to skip the update of machine->usb in the board init function.

On sPAPR we haven't supported boot once ever since it emerged, but
recently grew need for it. This patch implements boot once logic
to it.
While at it, we also move to the new bootdevice handling that got
introduced to the tree recently.

This fixes potential runtime crashes and two warnings from Coverity.
The new error message does not add a prefix "qemu:" because that is
already done in function hw_error. It also starts with an uppercase
letter because that seems to be the mostly used form.

memory_region_allocate_system_memory
Commit 0b183fc871:"memory: move mem_path handling to
memory_region_allocate_system_memory" split memory_region_init_ram and
memory_region_init_ram_from_file. Also it moved mem-path handling a step
up from memory_region_init_ram to memory_region_allocate_system_memory.
Therefore for any board that uses memory_region_init_ram directly,
-mem-path is not supported.
Fix this by replacing memory_region_init_ram with
memory_region_allocate_system_memory.

We don't validate the backend queue numbers against bus limitation,
this will easily crash qemu if it exceeds the limitation which will
hit the abort() in virtio_del_queue(). An example is trying to
starting a virtio-net device with 256 queues. E.g:
./qemu-system-x86_64 -netdev tap,id=hn0,queues=256 -device
virtio-net-pci,netdev=hn0
Fixing this by doing the validation and fail early.

commit 9b70c1790acacae54d559d38ca69186a85040bb8
virtio-serial: switch to standard-headers
changes virtio_console_config size from 8 to 12 bytes:
it adds an optional 4 byte emerg_wr field.
As this crosses a power of two boundary, this changes the PCI BAR size,
which breaks migration compatibility with old qemu machine types.
It's probably a problem for other transports as well.
As a temporary fix, as we don't yet support this new field anyway,
simply make the config size smaller at init time.
Long terms we probably want something along the lines
of virtio_net_set_config_size.

It is wrong to use address_space_memory directly, because there could be an
IOMMU in the middle. Passing the entire PVSCSIRingInfo to RS_GET_FIELD
and RS_SET_FIELD makes it easy to go back to the PVSCSIState.
