8244166dec migration/dirtyrate: Refactor dirty page rate calculation
abstract out dirty log change logic into function
global_dirty_log_change.

abstract out dirty page rate calculation logic via
dirty-ring into function vcpu_calculate_dirtyrate.

abstract out mathematical dirty page rate calculation
into do_calculate_dirtyrate, decouple it from DirtyStat.

rename set_sample_page_period to dirty_stat_wait, which
is well-understood and will be reused in dirtylimit.

handle cpu hotplug/unplug scenario during measurement of
dirty page rate.

export util functions outside migration.

ab1a161fe3 cpus: Introduce cpu_list_generation_id
Introduce cpu_list_generation_id to track cpu list generation so
that cpu hotplug/unplug can be detected during measurement of
dirty page rate.

cpu_list_generation_id could be used to detect changes of cpu
list, which is prepared for dirty page rate measurement.

c8ddcdd688 dbus-display: fix test race when initializing p2p connection
The D-Bus connection starts processing messages before QEMU has the time
to set the object manager server. This is causing dbus-display-test to
fail randomly with:

ERROR:../tests/qtest/dbus-display-test.c:68:test_dbus_display_vm:
assertion failed
(qemu_dbus_display1_vm_get_name(QEMU_DBUS_DISPLAY1_VM(vm)) ==
"dbus-test"): (NULL == "dbus-test") ERROR

Use the delayed message processing flag and method to avoid that
situation.

(the bus connection doesn't need a fix, as the initialization is done
synchronously)

1b7bd0abe9 lasips2: update VMStateDescription for LASIPS2 device
Since this series has already introduced a migration break for the HPPA B160L
machine, we can use this opportunity to improve the VMStateDescription for
the LASIPS2 device.

Add the new int_status field to the VMStateDescription and remodel the ports
as separate VMSTATE_STRUCT instances representing each LASIPS2Port. Once this
is done, the migration stream can be updated to include buf and loopback_rbne
for each port (which is necessary since the values are accessed across separate
IO accesses), and drop the port id as this is hardcoded for each port type.

212a300303 lasips2: switch to using port-based IRQs
Now we can implement port-based IRQs by wiring the PS2 device IRQs to the
LASI2Port named input gpios rather than directly to the LASIPS2 device, and
generate the LASIPS2 output IRQ from the int_status bitmap representing the
individual port IRQs instead of the birq boolean.

This enables us to remove the separate PS2 keyboard and PS2 mouse named input
gpios from the LASIPS2 device and simplify the register implementation to
drive the port IRQ using qemu_set_irq() rather than accessing the LASIPS2
device IRQs directly. As a consequence the IRQ level logic in lasips2_set_irq()
can also be simplified accordingly.

For now this patch ignores adding the int_status bitmap and simply drops the
birq boolean from the vmstate_lasips2 VMStateDescription. This is because the
migration stream is already missing some required LASIPS2 fields, and as this
series already introduces a migration break for the lasips2 device it is
easiest to fix this in a follow-up patch.
