60dc3c5be9 vhost: add method vhost_set_vring_err
Kernel and user vhost may report virtqueue errors via eventfd.

71e3d00482 msi: fix MSI vector limit check in msi_set_mask()
MSI supports a maximum of PCI_MSI_VECTORS_MAX vectors - from 0 to
PCI_MSI_VECTORS_MAX - 1.

msi_set_mask() was previously using PCI_MSI_VECTORS_MAX as the upper
limit for MSI vectors. Fix the upper limit to PCI_MSI_VECTORS_MAX - 1.

45461aace8 virtio-iommu: Fix the partial copy of probe request
The structure of probe request doesn't include the tail, this leads
to a few field missed to be copied. Currently this isn't an issue as
those missed field belong to reserved field, just in case reserved
field will be used in the future.

Changed 4th parameter of virtio_iommu_iov_to_req() to receive size
of device-readable part.

7227de94ad ps2: remove update_irq() function and update_arg parameter
Now that all the PS2 devices have been converted to use GPIOs the update_irq()
callback function and the update_arg parameter can be removed.

This allows these arguments to be completely removed from ps2_kbd_init() and
ps2_mouse_init(), along with the transitional logic that was added to
ps2_raise_irq() and ps2_lower_irq().

5cbf35d20f lasips2: rename lasips2_init() to lasips2_initfn() and update it to return the LASIPS2 device
When QOMifying a device it is typical to use _init() as the suffix for an
instance_init function, however this name is already in use by the legacy LASIPS2
wrapper function. Eventually the wrapper function will be removed, but for now
rename it to lasips2_initfn() to avoid a naming collision.

At the same time update lasips2_initfn() return the LASIPS2 device so that it
can later be accessed using qdev APIs by the HPPA machine.

75877e9356 pckbd: more vmstate_register() from i8042_mm_init() to i8042_mmio_realize()
Note in this case it is not possible to register a (new) VMStateDescription in
the DeviceClass without breaking migration compatibility for the MIPS magnum
machine.

01d924dce8 pckbd: move mapping of I8042_MMIO registers to MIPS magnum machine
Now that the register memory region is exposed as a SysBus memory region, move
the mapping of the I8042_MMIO registers from i8042_mm_init() to the MIPS magnum
machine (which is its only user).
