When the OHCI controller's framenumber is incremented, HccaPad1 register
should be set to zero (Ref OHCI Spec 4.4)
ReactOS uses hccaPad1 to determine if the OHCI hardware is running,
consequently it fails this check in current qemu master.

This reverts commit b320e21c48,
which accidentally broke TCG, because it made the TCG -cpu max
report the presence of MTE to the guest even if the board hadn't
enabled MTE by wiring up the tag RAM. This meant that if the guest
then tried to use MTE QEMU would segfault accessing the
non-existent tag RAM:

It's also not clear that the KVM logic is correct either:
MTE defaults to on there, rather than being only on if the
board wants it on.
Revert the whole commit for now so we can sort out the issues.
(We didn't catch this in CI because we have no test cases in
avocado that use guests with MTE support.)

Unlike pam_update() which takes the subject -- PAMMemoryRegion -- as
first argument, init_pam() takes it as fifth (!) argument. This makes it
quite hard to figure out what an init_pam() invocation actually
initializes. By moving the subject to the front this should become
clearer.
While at it, lower the DeviceState parameter to Object, also
communicating more clearly that this parameter is just the owner rather
than some (heavy?) dependency.

Let's just support 512 memslots on x86-64 and aarch64 as well. The maximum
number of ACPI slots (256) is no longer completely expressive ever since
we supported virtio-based memory devices. Further, we're completely
ignoring other memslots used outside of memory device context, such as
memslots used for boot memory.
Note that the vhost memslot limit in the kernel is usually configured to
be 509. With this change, we prepare vhost-user on the QEMU side to be
closer to that limit, to eventually support ~512 memslots in most vhost
implementations and have less "surprises" when cold/hotplugging vhost
devices while also consuming more memslots than we're currently used to
by memory devices (e.g., once virtio-mem starts using multiple memslots).
Note that most vhost-user implementations only support a small number of
memslots so far, which we can hopefully improve in the near future.
We'll leave the PPC special-case as is for now.

Allowing guests to read unplugged memory simplified the bring-up of
virtio-mem in Linux guests -- which was limited to x86-64 only. On arm64
(which was added later), we never had legacy guests and don't even allow
to configure it, essentially always having "unplugged-inaccessible=on".
At this point, all guests we care about
should be supporting VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE, so let's
change the default for the 8.1 machine.
This change implies that also memory that supports the shared zeropage
(private anonymous memory) will now require
VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE in the driver in order to be usable by
the guest -- as default, one can still manually set the
unplugged-inaccessible property.
Disallowing the guest to read unplugged memory will be important for
some future features, such as memslot optimizations or protection of
unplugged memory, whereby we'll actually no longer allow the guest to
even read from unplugged memory.
At some point, we might want to deprecate and remove that property.

Setting the VIRTIO Device Status Field to 0 resets the device. The
device's state is lost, including the vring configuration.
vhost-user.c currently sends SET_STATUS 0 before GET_VRING_BASE. This
risks confusion about the lifetime of the vhost-user state (e.g. vring
last_avail_idx) across VIRTIO device reset.
Eugenio Pérez <eperezma@redhat.com> adjusted the order for vhost-vdpa.c
in commit c3716f260b ("vdpa: move vhost reset after get vring base")
and in that commit description suggested doing the same for vhost-user
in the future.
Go ahead and adjust vhost-user.c now. I ran various online code searches
to identify vhost-user backends implementing SET_STATUS. It seems only
DPDK implements SET_STATUS and Yajun Wu <yajunw@nvidia.com> has
confirmed that it is safe to make this change.

This commit enables each CXL Type-3 device to contain one volatile
memory region and one persistent region.
Two new properties have been added to cxl-type3 device initialization:
[volatile-memdev] and [persistent-memdev]
The existing [memdev] property has been deprecated and will default the
memory region to a persistent memory region (although a user may assign
the region to a ram or file backed region). It cannot be used in
combination with the new [persistent-memdev] property.
Partitioning volatile memory from persistent memory is not yet supported.
Volatile memory is mapped at DPA(0x0), while Persistent memory is mapped
at DPA(vmem->size), per CXL Spec 8.2.9.8.2.0 - Get Partition Info.

QEMU invokes vhost_svq_add() when adding a guest's element
into SVQ. In vhost_svq_add(), it uses vhost_svq_available_slots()
to check whether QEMU can add the element into SVQ. If there is
enough space, then QEMU combines some out descriptors and some
in descriptors into one descriptor chain, and adds it into
`svq->vring.desc` by vhost_svq_vring_write_descs().
Yet the problem is that, `svq->shadow_avail_idx - svq->shadow_used_idx`
in vhost_svq_available_slots() returns the number of occupied elements,
or the number of descriptor chains, instead of the number of occupied
descriptors, which may cause wrapping in SVQ descriptor ring.
Here is an example. In vhost_handle_guest_kick(), QEMU forwards
as many available buffers to device by virtqueue_pop() and
vhost_svq_add_element(). virtqueue_pop() returns a guest's element,
and then this element is added into SVQ by vhost_svq_add_element(),
a wrapper to vhost_svq_add(). If QEMU invokes virtqueue_pop() and
vhost_svq_add_element() `svq->vring.num` times,
vhost_svq_available_slots() thinks QEMU just ran out of slots and
everything should work fine. But in fact, virtqueue_pop() returns
`svq->vring.num` elements or descriptor chains, more than
`svq->vring.num` descriptors due to guest memory fragmentation,
and this causes wrapping in SVQ descriptor ring.
This bug is valid even before marking the descriptors used.
If the guest memory is fragmented, SVQ must add chains
so it can try to add more descriptors than possible.
This patch solves it by adding `num_free` field in
VhostShadowVirtqueue structure and updating this field
in vhost_svq_add() and vhost_svq_get_buf(), to record
the number of free descriptors.

In the vexpress board code, we allocate a new MemoryRegion at the top
of vexpress_common_init() but only set it up and use it inside the
"if (map[VE_NORFLASHALIAS] != -1)" conditional, so we leak it if not.
This isn't a very interesting leak as it's a tiny amount of memory
once at startup, but it's easy to fix.
We could silence Coverity simply by moving the g_new() into the
if() block, but this use of g_new(MemoryRegion, 1) is a legacy from
when this board model was originally written; we wouldn't do that
if we wrote it today. The MemoryRegions are conceptually a part of
the board and must not go away until the whole board is done with
(at the end of the simulation), so they belong in its state struct.
This machine already has a VexpressMachineState struct that extends
MachineState, so statically put the MemoryRegions in there instead of
dynamically allocating them separately at runtime.
