This is then usable by clients, where the control logic for send

if (send)
   i2c_send(...):
else
   i2c_recv(...);

becomes:

i2c_send_recv(... , send);

If qdev_try_create() is passed NULL for the bus, it will automatically
put the newly created device onto the default system bus. However
if the device is not actually a SysBusDevice then this will result
in later crashes (for instance when running the monitor "info qtree"
command) because code reasonably assumes that all devices on the system
bus are system bus devices.

Generally the mistake is that the calling code should create the
object with object_new(TYPE_FOO) rather than qdev_create(NULL, TYPE_FOO);
see commit 6749695e for an example of fixing this bug.

Assert in qdev_try_create() if the device isn't suitable to put on
the system bus, so that this mistake results in failure earlier
and more reliably.

The sclp scp read info call fills in a buffer with information about the
system. With more than 248 CPUs we overflow the 4k buffer of the SCCB,
leading to random data corruption. Basically ALL guest operating systems
call scp read info, so let's limit the machines to 248 CPUs to make it
obvious that >=249 does not work.

As KVM also limits itself to 248 and TCG on s390 does not support
SMP, this should cause no regression for any user as no VMs with more
than 248 VCPUs were ever possible.

Let's introduce a CssDevId to handle device ids of the xx.x.xxxx

- We can use them in virtio-ccw and split the validity checks for
  a channel device id in general from the constraint checking
  within the virtio-ccw scope.
- We can reuse the device id type for future non-virtio channel
  devices.

While we're at it, improve the validity checks and disallow e.g.
trailing characters.

According to the Principles of Operation (more precisely the subsection
'Channel-Report Word'), a subchannel put into the installed parameters
initialized state is in the same state as after an I/O system reset (just
parameters possibly changed). This implies that any I/O interrupts for that
subchannel are no longer pending (as I/O system resets clear I/O
interrupts). Therefore, we need an interface to clear pending I/O
interrupts. Make css_generate_sch_crws clear the pending IO interrupts for

Memory hotplug can fail for some combinations of RAM and maxmem when
DDW is enabled in the presence of devices like nec-usb-xhci. DDW depends
on maximum addressable memory returned by guest and this value is currently
being calculated wrongly by the guest kernel routine memory_hotplug_max().
While there is an attempt to fix the guest kernel, this patch works
around the problem within QEMU itself.

memory_hotplug_max() routine in the guest kernel arrives at max
addressable memory by multiplying lmb-size with the lmb-count obtained
from ibm,dynamic-memory property. There are two assumptions here:

- All LMBs are part of ibm,dynamic memory: This is not true for PowerKVM
  where only hot-pluggable LMBs are present in this property.
- The memory area comprising of RAM and hotplug region is contiguous: This
  needn't be true always for PowerKVM as there can be gap between
  boot time RAM and hotplug region.

To work around this guest kernel bug, ensure that ibm,dynamic-memory
has information about all the LMBs (RMA, boot-time LMBs, future
hotpluggable LMBs, and dummy LMBs to cover the gap between RAM and
hotpluggable region).

RMA is represented separately by memory@0 node. Hence mark RMA LMBs
and also the LMBs for the gap b/n RAM and hotpluggable region as
reserved and as having no valid DRC so that these LMBs are not considered
by the guest.
