265b578c58 object: fix OBJ_PROP_LINK_UNREF_ON_RELEASE ambivalence
A link property can be set during creation, with
object_property_add_link() and later with object_property_set_link().

add_link() doesn't add a reference to the target object, while
set_link() does.

Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link,
says whether a reference must be released when the property is destroyed.
This can lead to leaks if the property was later set_link(), as the
added reference is never released.

Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG
and use that has an indication on how the link handle reference
management in set_link().

d638fd5c96 mos6522: move timer frequency initialisation to mos6522_reset
The 6522 VIA timer frequency cannot be set by altering registers within the
device itself and hence it is a fixed property of the machine.

Move the initialisation of the timer frequency to the mos6522 reset function
and ensure that any subclasses always call the parent reset function so that
it isn't required to store the timer frequency within vmstate_mos6522_timer
itself.

By moving the frequency initialisation to the device reset function then we
find that the realize function for both mos6522 and mos6522_cuda becomes
obsolete and can simply be removed.

2e3e5c7e92 cuda: embed mos6522_cuda device directly rather than using QOM object link
Examining the migration stream it can be seen that the mos6522 device state is
being stored separately rather than as part of the CUDA device which is
incorrect (and likely to cause issues if another mos6522 device is added to
the machine).

Resolve this by embedding the mos6522_cuda device directly within the CUDA
device rather than using a QOM object link to reference the device separately.

Note that we also bump the version in vmstate_cuda to reflect this change: this
isn't particularly important for the moment as the Mac machine migration isn't
100% reliable due to issues migrating the timebase under TCG.

bdrv_is_writable_after_reopen() create a new bdrv_is_writable() function
that just passes NULL to it for the reopen queue.

mode. The device also supports two blinking rates but not the model
yet.

910e204841 arm_gicv3_kvm: kvm_dist_get/put: skip the registers banked by GICR
While we skip the GIC_INTERNAL irqs, we don't change the register offset
accordingly. This will overlap the GICR registers value and leave the
last GIC_INTERNAL irq's registers out of update.

Fix this by skipping the registers banked by GICR.

Also for migration compatibility if the migration source (old version
qemu) doesn't send gicd_no_migration_shift_bug = 1 to destination, then
we shift the data of PPI to get the right data for SPI.

b895de5027 migration: discard non-migratable RAMBlocks
On the POWER9 processor, the XIVE interrupt controller can control
interrupt sources using MMIO to trigger events, to EOI or to turn off
the sources. Priority management and interrupt acknowledgment is also
controlled by MMIO in the presenter sub-engine.

These MMIO regions are exposed to guests in QEMU with a set of 'ram
device' memory mappings, similarly to VFIO, and the VMAs are populated
dynamically with the appropriate pages using a fault handler.

But, these regions are an issue for migration. We need to discard the
associated RAMBlocks from the RAM state on the source VM and let the
destination VM rebuild the memory mappings on the new host in the
post_load() operation just before resuming the system.

To achieve this goal, the following introduces a new RAMBlock flag
RAM_MIGRATABLE which is updated in the vmstate_register_ram() and
vmstate_unregister_ram() routines. This flag is then used by the
migration to identify RAMBlocks to discard on the source. Some checks
are also performed on the destination to make sure nothing invalid was
sent.

This change impacts the boston, malta and jazz mips boards for which
migration compatibility is broken.

f548222c24 migration: introduce decompress-error-check
QEMU 3.0 enables strict check for compression & decompression to
make the migration more robust, that depends on the source to fix
the internal design which triggers the unexpected error conditions

To make it work for migrating old version QEMU to 2.13 QEMU, we
introduce this parameter to disable the error check on the
destination which is the default behavior of the machine type
which is older than 2.13, alternately, the strict check can be
enabled explicitly as followings:
      -M pc-q35-2.11 -global migration.decompress-error-check=true

a8bff79e9f virtio-gpu-3d: Define VIRTIO_GPU_CAPSET_VIRGL2 elsewhere
Commit 5643cc94ac ("virtio-gpu-3d: add support for second capability
set (v4)") updated virtio_gpu.h with a define that does not yet(?)
exist upstream resulting in build breakage every time Linux headers
are updated via the standard update script.  Conditionally define this
within QEMU code instead to avoid future breakage.

257a7430e7 memory: get rid of memory_region_init_reservation
The function has been deprecated for 2.5 years, and there are just a handful
of users.  Convert them to memory_region_init_io with NULL callbacks,
and while at it pass the right device as the owner.
