When running a pseries-2.2 or older machine type, we get the following
lines in info mtree:
address-space: memory
...
ffffffffffffffff-ffffffffffffffff (prio 0, i/o): alias
pci@800000020000000.mmio64-alias @pci@800000020000000.mmio
ffffffffffffffff-ffffffffffffffff

pci@800000020000000.mmio64-alias @pci@800000020000000.mmio
ffffffffffffffff-ffffffffffffffff
The same thing occurs when running a pseries-2.7 with
-global spapr-pci-host-bridge.mem_win_size=2147483648
This happens because we always create a 64-bit MMIO window, even if
we didn't explicitely requested it (ie, mem64_win_size == 0) and the
32-bit window is below 2GiB. It doesn't seem to have an impact on the
guest though because spapr_populate_pci_dt() doesn't advertise the
bogus windows when mem64_win_size == 0.
Since these memory regions don't induce any state, we can safely
choose to not create them when their address is equal to -1,
without breaking migration from existing setups.

If object_property_get_link() fails then it allocates an error, which
must be freed before returning. The error_get_pretty() function is
merely an accessor to the error message and doesn't free anything.
The error.h header indicates how to do it right:
* Pass an existing error to the caller with the message modified:
* error_propagate(errp, err);
* error_prepend(errp, "Could not frobnicate '%s': ", name);

The existing tries to round up the number of pages but @pages is always
calculated as the rounded up value minus one which makes ctz64() always
return 0 and have create.levels always set 1.
This removes wrong "-1" and allows having more than 1 levels. This becomes
handy for >128GB guests with standard 64K pages as this requires blocks
with zone order 9 and the popular limit of CONFIG_FORCE_MAX_ZONEORDER=9
means that only blocks up to order 8 are allowed.

libfdt failures when creating the FDT should cause QEMU to terminate.
Let's use the _FDT() macro which does just that instead of propagating

The OV5_MMU_RADIX_300 requires special handling in the CAS negotiation
process. It is cleared from the option vector of the guest before
evaluating the changes and re-added later. But, when testing for a
possible CAS reset :
spapr->cas_reboot = spapr_ovec_diff(ov5_updates,
ov5_cas_old, spapr->ov5_cas);
the bit OV5_MMU_RADIX_300 will each time be seen as removed from the
previous OV5 set, hence generating a reset loop.
Fix this problem by also clearing the same bit in the ov5_cas_old set.

Commit b55d295e3e added the possibility to support HPT resizing with KVM.
In the case of PR, we need to pass the userspace address of the HPT to KVM
using the SDR1 slot.
This is handled by kvmppc_update_sdr1() which uses CPU_FOREACH() to update
all CPUs. It is hence not needed to call kvmppc_update_sdr1() for each CPU.

This patch removes the qdev_get_machine() calls that are made in
spapr.c in situations where we can get an existing pointer for
the MachineState by either passing it as an argument to the function
or by using other already available pointers.
The following changes were made:
- spapr_node0_size: static function that is called two times:
at spapr_setup_hpt_and_vrma and ppc_spapr_init. In both cases we can
pass an existing MachineState pointer to it.
- spapr_build_fdt: MachineState pointer can be retrieved from
the existing sPAPRMachineState pointer.
- spapr_boot_set: the opaque in the first arg is a sPAPRMachineState
pointer as we can see inside ppc_spapr_init:
qemu_register_boot_set(spapr_boot_set, spapr);
We can get a MachineState pointer from it.
- spapr_machine_device_plug and spapr_machine_device_unplug_request: the
MachineState, sPAPRMachineState, MachineClass and sPAPRMachineClass pointers
can all be retrieved from the HotplugHandler pointer.

This adds a simplistic emulation of the Sun GEM ethernet controller
found in Apple ASICs.
Currently we only support the Apple UniNorth 1.x variant, but the
other Apple or Sun variants should mostly be a matter of adding
PCI IDs options.
We have a very primitive emulation of a single Broadcom 5201 PHY
which is supported by the MacOS driver.
This model brings out-of-the-box networking to MacOS 9, and all
versions of OS X I tried with the mac99 platform.
Further improvements from Mark:
- Remove sungem.h file, moving constants into sungem.c as required
- Switch to using tracepoints for debugging
- Split register blocks into separate memory regions
- Use arrays in SunGEMState to hold register values
- Add state-saving support
