Now that the driver core can properly handle constant struct bus_type,
move the virtio_bus variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.

IFCVF HW supports operation with vq size less than the max size,
as the spec required.
This commit implements vdpa_config_ops.get_vq_num_min to report
the minimal size of the virtqueues, which gives vDPA framework
a chance to reduce the vring size.
We need at least one descriptor to be functional, but it is better
no less than 64 to meet ceratin performance requirements.
Actually the framework would allocate at least a PAGE for the vq.

This addresses a couple of things found while testing the FLR and AER

- release irqs before calling vp_modern_remove()
- make sure we have a valid struct pointer before using it to release irqs
- make sure the FW is alive before trying to add a new device

Since commit 295525e29a5b ("virtio_net: merge dma
operations when filling mergeable buffers"), VDUSE device
require support for DMA's .sync_single_for_cpu() operation
as the memory is non-coherent between the device and CPU
because of the use of a bounce buffer.
This patch implements both .sync_single_for_cpu() and
.sync_single_for_device() callbacks, and also skip bounce
buffer copies during DMA map and unmap operations if the
DMA_ATTR_SKIP_CPU_SYNC attribute is set to avoid extra
copies of the same buffer.

The MLX driver was not updating its control virtqueue size at set_vq_num
and instead always initialized to MLX5_CVQ_MAX_ENT (16) at
setup_cvq_vring.
Qemu would try to set the size to 64 by default, however, because the
CVQ size always was initialized to 16, an error would be thrown when
sending >16 control messages (as used-ring entry 17 is initialized to 0).
For example, starting a guest with x-svq=on and then executing the
following command would produce the error below:
# for i in {1..20}; do ifconfig eth0 hw ether XX:xx:XX:xx:XX:XX; done

Currently, we don't reenable the config if freezing the device failed.
For example, virtio-mem currently doesn't support suspend+resume, and
trying to freeze the device will always fail. Afterwards, the device
will no longer respond to resize requests, because it won't get notified
about config changes.
Let's fix this by re-enabling the config if freezing fails.

When the Qemu launched with vhost but without tap vnet_hdr,
vhost tries to copy vnet_hdr from socket iter with size 0
to the page that may contain some trash.
That trash can be interpreted as unpredictable values for
vnet_hdr.
That leads to dropping some packets and in some cases to
stalling vhost routine when the vhost_net tries to process
packets and fails in a loop.
Qemu options:
-netdev tap,vhost=on,vnet_hdr=off,...

Pull firewire fix from Takashi Sakamoto:
"A fix to suppress a warning about unreleased IRQ for 1394 OHCI
hardware when disabling MSI.
In Linux kernel v6.5, a PCI driver for 1394 OHCI hardware was
optimized into the managed device resources. Edmund Raile points out
that the change brings the warning about unreleased IRQ at the call of
pci_disable_msi(), since the API expects that the relevant IRQ has
already been released in advance.
As long as the API is called in .remove callback of PCI device
operation, it is prohibited to maintain the IRQ as the part of managed
device resource. As a workaround, the IRQ is explicitly released at
.remove callback, before the call of pci_disable_msi().
pci_disable_msi() is legacy API nowadays in PCI MSI implementation. I
have a plan to replace it with the modern API in the development for
the future version of Linux kernel. So at present I keep them as is"

When the i2c error condition occurred and master state was not
idle, the master irq function will goto complete state without any
other interrupt handling. It would cause dummy irq expected print.
Under this condition, assign the irq_status into irq_handle.
For example, when the abnormal start / stop occurred (bit 5) with
normal stop status (bit 4) at same time. Then the normal stop status
would not be handled and it would cause irq expected print in
the aspeed_i2c_bus_irq.

Calling irq_domain_remove() will lead to freeing the IRQ domain
prematurely. The domain is still referenced and will be attempted to get
used via rmi_free_function_list() -> rmi_unregister_function() ->
irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer.
With PaX's MEMORY_SANITIZE this will lead to an access fault when
attempting to dereference embedded pointers, as in Torsten's report that
was faulting on the 'domain->ops->unmap' test.
Fix this by releasing the IRQ domain only after all related IRQs have
been deactivated.

When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), Callback function pdsc_auxbus_dev_release
calls kfree(padev) to free memory. We shouldn't call kfree(padev)
again in the error handling path.
Fix this by cleaning up the redundant kfree() and putting
the error handling back to where the errors happened.

As the chip selects can be configured through ACPI/OF/swnode, and
the set_cs() callback will only be called when a native chip select
is being used, there is no reason for the driver to only support the
native chip select as the first chip select. Remove the check that
introduces this limitation.
