I was hoping to get this pull request squeezed in before the soft
freeze, but I ran into some difficulties during testing. Everything
here was at least posted before the soft freeze, so I'm hoping we can
still merge it for 2.9.
The biggest things here are:
* Cleanups to handling of hashed page tables, that will make
adding support for the POWER9 MMU easier
* Cleanups to the XICS interrupt controller that will make
implementing the powernv machine easier
* TCG implementation of extended overflow and carry handling for
POWER9
It also includes:
* Increasing the CPU limit for pseries to 1024 vCPUs
* Generating proper OF node names in qemu (making hotplug and
coldplug logic closer together)

Apparently, none of the bus owner give a reference to the hotplug
handler property, do not unref it on bus release.
Furthermore, a bus is allowed to be its own hotplug handler, which can
be seen in qbus_set_bus_hotplug_handler() function. However, in this
case, the reference can't be given to the property, or this will create
a cyclic dependency and the bus will never be free.
Each bus owner should manage the lifecycle of the hotplug handler.

PCI hotplug for bridges was introduced only since 2.0 however
acpi_set_bsel()->object_property_add_uint32_ptr(bus, ACPI_PCIHP_PROP_BSEL)
didn't take in account that for legacy mode (1.7) when
PCI hotplug for bridges is unavailable and ACPI_PCIHP_PROP_BSEL property
the only bus "PCI.0' has been created earlier at acpi_pcihp_init() time.
We managed to live with it only because of error rised by adding
a duplicate property in acpi_set_bsel() has been ignored which
resulted in useless leaking of just allocated (int)bus_bsel.
Issue affects only 1.7 machine type as ACPI tables supported by
QEMU were introduced at that time, but there wasn't PCI hotplug
for bridges till the next release (2.0).
Fix it by removing duplicate ACPI_PCIHP_PROP_BSEL intialization
in acpi_pcihp_init() and doing it only in one place acpi_set_pci_info().
PS:
do not ignore error returned by object_property_add_uint32_ptr()
and abort QEMU since it's programming error which should be fixed
instead of being ignored.

This patch extends support for the `dump-guest-memory` command to the
32-bit PowerPC architecture. It relies on the assumption that a 64-bit
guest will not dump a 32-bit core file (and vice versa).
[dwg: I suspect this patch won't cover all cases, in particular a
32-bit machine type on a 64-bit qemu build. However, it does strictly
more than what we had before, so might as well apply as a starting
point]

The ICS object uses a post_load() handler which is implicitly relying
on the fact that the internal state of the ICS and ICP objects has
been restored but this is not guaranteed. So, let's move the code
under the post_load() handler of the machine where we know the objects
have been fully restored.
The icp_resend() handler of the XICSFabric QOM interface is also
removed as it is now obsolete.

The XICSState classes are not used anymore. They have now been fully
deprecated by the XICSFabric QOM interface. Do the cleanups.

There is nothing left related to the XICS object in the realize
functions of the KVMXICSState and XICSState class. So adapt the
interfaces to call these routines directly from the sPAPR machine init
sequence.

This is the last step to remove the XICSState abstraction and have the
machine hold all the objects related to interrupts : ICSs and ICPs.

The reset of the ICP objects is currently handled by XICS but this can
be done for each individual ICP.

spapr_dt_xics() only needs the number of servers to build the device
tree nodes. Let's change the routine interface to reflect that.

The cpu_setup() handler is currently under the XICSState class but it
really belongs under ICPState as it is setting up an individual vCPU.

The cpu_setup() handler currently takes a 'XICSState *' argument to
grab the kernel ICP file descriptor. This interface can be simplified
by using the 'xics' backlink of the ICP object.
This change is also required by subsequent patches which makes use of
the QOM interface for XICS.

The kernel ICP file descriptor is the only reason behind the
KVMXICSState class and it's in the way of more cleanups. Let's make it
a static for the moment and move forward.
If this is problem, we could use an attribute under the sPAPR machine
later on.

Let's add two new handlers for ICPs. One is to get an ICP object from
a server number and a second is to resend the irqs when needed.
The icp_resend() handler is a temporary workaround needed by the
ics-simple post_load() handler. It will be removed when the post_load
portion can be done at the machine level.
