66f37d360b vl: smp_parse: fix regression
Commit 0544edd88a "vl: smp_parse: cleanups" regressed any -smp
config that left either cores or threads unspecified, and specified
a topology supporting more cpus than the given online cpus. The
correct way to calculate the missing parameter would be to use
maxcpus, but it's too late to change that now. Restore the old
way, which is to calculate it with the online cpus (as is still
done), but then, if the result is zero, just set it to one.

ea5d42508c ICH9 LPC: move call of isa_bus_irqs to 'realize' method
The isa_bus_irqs function initializes ISA bus IRQ array pointer with specified
value.

Previously the ICH9 LPC bridge model did not have its own IRQs but
only IRQ pointer cache. And same GSI were used for ISA bus and other sources
behind the bridge (PCI, SCI). Hence, the pc_q35_init was only possible place to
setup both ISA bus IRQs and the bridge IRQ cache.

As a result, the call of isa_bus_irqs was made from pc_q35_init.

Now the ICH9 LPC bridge has its own output IRQs which are connected to GSI. The
output IRQs are already used to route IRQs from PCI and SCI.

The patch makes the ICH9 LPC bridge output IRQs to used for ISA bus too.

1f3aba377d pc: acpi: drop intermediate PCMachineState.node_cpu
PCMachineState.node_cpu was used for mapping APIC ID
to numa node id as CPU entries in SRAT used to be
built on sparse APIC ID bitmap (up to apic_id_limit).
However since commit
  5803fce pc: acpi: SRAT: create only valid processor lapic entries
CPU entries in SRAT aren't build using apic bitmap
but using 0..maxcpus index instead which is also used
for creating numa_info[x].node_cpu map.
So instead of doing useless intermediate conversion from
  1. node by cpu index -> node by apic id
       i.e. numa_info[x].node_cpu -> PCMachineState.node_cpu
  2. apic id -> srat entry PMX
       PCMachineState.node_cpu[apic id] -> PMX value
use numa_info[x].node_cpu map directly like ARM does and do
  1. numa_info[x].node_cpu -> PMX value using index
     in range 0..maxcpus
and drop not necessary PCMachineState.node_cpu and related
code.

That also removes the last (not counting legacy hotplug)
dependency of ACPI code on apic_id_limit and need to allocate
huge sparse PCMachineState.node_cpu array in case of 32-bit
APIC IDs.
