It's arguably a bug in Clang since we already use __builtin_assume_aligned()
to tell the compiler that the pointer is properly aligned. But according to
https://github.com/llvm/llvm-project/issues/69146 it seems like the Clang
folks don't see an easy fix on their side and recommend to use a type
declared with __attribute__((aligned(16))) to work around this problem.

Until now, array properties are actually implemented with a hack that
uses multiple properties on the QOM level: a static "foo-len" property
and after it is set, dynamically created "foo[i]" properties.
In external interfaces (-device on the command line and device_add in
QMP), this interface was broken by commit f3558b1b ('qdev: Base object
creation on QDict rather than QemuOpts') because QDicts are unordered
and therefore it could happen that QEMU tried to set the indexed
properties before setting the length, which fails and effectively makes
array properties inaccessible. In particular, this affects the 'ports'
property of the 'rocker' device, which used to be configured like this:
-device rocker,len-ports=2,ports[0]=dev0,ports[1]=dev1
This patch reworks the external interface so that instead of using a
separate top-level property for the length and for each element, we use
a single true array property that accepts a list value. In the external
interfaces, this is naturally expressed as a JSON list and makes array
properties accessible again. The new syntax looks like this:
-device '{"driver":"rocker","ports":["dev0","dev1"]}'
Creating an array property on the command line without using JSON format
is currently not possible. This could be fixed by switching from
QemuOpts to a keyval parser, which however requires consideration of the
compatibility implications.
All internal users of devices with array properties go through
qdev_prop_set_array() at this point, so updating it takes care of all of
them.

bdrv_change_backing_file() is called both inside and outside coroutine
context. This makes it difficult for it to take the graph lock
internally. It also means that driver implementations need to be able to
run outside of coroutines, too. Switch it to the usual model with a
coroutine based implementation and a co_wrapper instead. The new
function is marked GRAPH_RDLOCK.
As the co_wrapper now runs the function in the AioContext of the node
(as it should always have done), this is not GLOBAL_STATE_CODE() any
more.

Power9 is supposed to have 4 PIB-connected I2C engines with the
following number of ports on each engine:
0: 2
1: 13
2: 2
3: 2
Power10 also has 4 engines but has the following number of ports
on each engine:
0: 14
1: 14
2: 2
3: 16
Current code assumes that they all have the same (maximum) number.
This can be a problem if software expects to see a certain number
of ports present (Power Hypervisor seems to care).
Fixed this by adding separate tables for power9 and power10 that
map the I2C controller number to the number of I2C buses that should
be attached for that engine.

The more recent IBM power processors have an embedded I2C
controller that is accessible by software via the XSCOM
address space.
Each instance of the I2C controller is capable of controlling
multiple I2C buses (one at a time). Prior to beginning a
transaction on an I2C bus, the bus must be selected by writing
the port number associated with the bus into the PORT_NUM
field of the MODE register. Once an I2C bus is selected,
the status of the bus can be determined by reading the
Status and Extended Status registers.
I2C bus transactions can be started by writing a command to
the Command register and reading/writing data from/to the
FIFO register.
Not supported :
. 10 bit I2C addresses

Following the example documented since commit e3fe3988d7 ("error:
Document Error API usage rules"), have cpu_exec_realizefn()
return a boolean indicating whether an error is set or not.

"hw/s390x/sclp.h" is a header used by target-agnostic objects
(such hw/char/sclpconsole[-lm].c), thus can not use target-specific
types, such CPUS390XState.
Have sclp_service_call[_protected]() take a S390CPU pointer, which
is target-agnostic.

The OBJECT_DECLARE_CPU_TYPE() macro forward-declares the
PowerPCCPUClass type. This forward declaration is sufficient
for code in hw/ to use the QOM definitions. No need to expose
the structure definition. Keep it local to target/ppc/ by
moving it to target/ppc/cpu.h.
