9812feefab vfio/container: Introduce a VFIOIOMMU legacy QOM interface
Convert the legacy VFIOIOMMUOps struct to the new VFIOIOMMU QOM
interface. The set of of operations for this backend can be referenced
with a literal typename instead of a C struct. This will simplify
support of multiple backends.

fdaa774e67 vfio/container: Introduce a VFIOIOMMU QOM interface
VFIOContainerBase was not introduced as an abstract QOM object because
it felt unnecessary to expose all the IOMMU backends to the QEMU
machine and human interface. However, we can still abstract the IOMMU
backend handlers using a QOM interface class. This provides more
flexibility when referencing the various implementations.

Simply transform the VFIOIOMMUOps struct in an InterfaceClass and do
some initial name replacements. Next changes will start converting
VFIOIOMMUOps.

bffe92af0e vfio/container: Initialize VFIOIOMMUOps under vfio_init_container()
vfio_init_container() already defines the IOMMU type of the container.
Do the same for the VFIOIOMMUOps struct. This prepares ground for the
following patches that will deduce the associated VFIOIOMMUOps struct
from the IOMMU type.

the correct spelling is "buses" (26 instances). Fixing those 5

2c5107e1b4 edu: fix DMA range upper bound check
The edu_check_range function checks that start <= end1 < end2, where
end1 is the upper bound (exclusive) of the guest-supplied DMA range and
end2 is the upper bound (exclusive) of the device's allowed DMA range.
When the guest tries to transfer exactly DMA_SIZE (4096) bytes, end1
will be equal to end2, so the check fails and QEMU aborts with this
puzzling error message (newlines added for formatting):

  qemu: hardware error: EDU: DMA range
    0x0000000000040000-0x0000000000040fff out of bounds
   (0x0000000000040000-0x0000000000040fff)!

By checking end1 <= end2 instead, guests will be allowed to transfer
exactly 4096 bytes. It is not necessary to explicitly check for
start <= end1 because the previous two checks (within(addr, start, end2)
and end1 > addr) imply start < end1.

25145a7d77 hw/net/can/sja1000: fix bug for single acceptance filter and standard frame
A CAN sja1000 standard frame filter mask has been computed and applied
incorrectly for standard frames when single Acceptance Filter Mode
(MOD_AFM = 1) has been selected. The problem has not been found
by Linux kernel testing because it uses dual filter mode (MOD_AFM = 0)
and leaves falters fully open.

The problem has been noticed by Grant Ramsay when testing with Zephyr
RTOS which uses single filter mode.

287fa32324 hw: Simplify accesses to the CPUState::'start-powered-off' property
The 'start-powered-off' property has been added to ARM CPUs in
commit 5de164304a ("arm: Allow secondary KVM CPUs to be booted
via PSCI"), then eventually got generalized to all CPUs in commit
c1b701587e ("target/arm: Move start-powered-off property to generic
CPUState"). Since all CPUs have it, no need to check whether it is
available. Updating this property can't fail, so use &error_abort.
