edd7541b8c fix "Missing break in switch" coverity reports
Many of these are marked as "intentional/fix required" because they
just need adding a fall through comment.  This is exactly what this
patch does, except for target/mips/translate.c where it is easier to
duplicate the code, and hw/audio/sb16.c where I consulted the DOSBox
sources and decide to just remove the LOG_UNIMP before the fallthrough.

Use the automatic subregister extraction from the memory API, and avoid
that Coverity complains about missing fallthrough comments.

06d09a018f tests: virtio: separate ccw tests from libqos
Because qtest does not support s390 channel I/O, s390 only performs smoke tests on
those few devices that do not have any functional tests.  Therefore, every time we
add functional tests for a virtio device, the choice is between removing
those tests from the s390 suite (so that s390 actually _loses_ coverage)
or sprinkling the test with architecture checks.

This patch simply creates a ccw-specific test that only performs smoke tests on
all virtio-ccw devices.  If channel I/O support is ever added to qtest and libqos,
then this file can go away.  In the meanwhile, it simplifies maintenance and
makes sure that all virtio devices are tested.

So when we translate the buffer we must check we don't go beyond the

3ac24188ec sun4u: ensure kernel_top is always initialised
Valgrind reports that when loading a non-ELF kernel, kernel_top may be used
uninitialised when checking for an initrd.

Since there are no known non-ELF kernels for SPARC64 then we can simply
initialise kernel_top to 0 and then skip the initrd load process if it hasn't
been set by load_elf().

09c6c75480 s390x: Enable KVM huge page backing support
QEMU has had huge page support for a longer time already, but KVM
memory management under s390x needed some changes to work with huge
backings.

Now that we have support, let's enable it if requested and
available. Otherwise we now properly tell the user if there is no
support and back out instead of failing to run the VM later on.

c61177881c s390x/cpumodel: Add "-cpu max" support
The "max" CPU model behaves like "-cpu host" when KVM is enabled, and like
a CPU with the maximum possible feature set when TCG is enabled.

While the "host" model can not be used under TCG ("kvm_required"), the
"max" model can and "Enables all features supported by the accelerator in
the current host".

So we can treat "host" just as a special case of "max" (like x86 does).
It differs to the "qemu" CPU model under TCG such that compatibility
handling will not be performed and that some experimental CPU features
not yet part of the "qemu" model might be indicated.

These are right now under TCG (see "qemu_MAX"):
- stfle53
- msa5-base
- zpci

This will result right now in the following warning when starting QEMU TCG
with the "max" model:
    "qemu-system-s390x: warning: 'msa5-base' requires 'kimd-sha-512'."

The "qemu" model (used as default in QEMU under TCG) will continue to
work without such warnings. The "max" model in the current form
might be interesting for kvm-unit-tests (where we would e.g. now also
test "msa5-base").

The "max" model is neither static nor migration safe (like the "host"
model). It is independent of the machine but dependends on the accelerator.
It can be used to detect the maximum CPU model also under TCG from upper
layers without having to care about CPU model names for CPU model
expansion.

b85fad1588 hw/dma/pl080: Remove hw_error() if DMA is enabled
The PL08x model currently will unconditionally call hw_error()
if the DMA engine is enabled by the guest. This has been
present since the PL080 model was edded in 2006, and is
presumably either unintentional debug code left enabled,
or a guard against untested DMA engine code being used.

Remove the hw_error(), since we now have a guest which
will actually try to use the DMA engine (the self-test
binary for the AN505 MPS2 FPGA image).

112a829f8f hw/dma/pl080: Don't use CPU address space for DMA accesses
Currently our PL080/PL081 model uses a combination of the CPU's
address space (via cpu_physical_memory_{read,write}()) and the
system address space for performing DMA accesses.

For the PL081s in the MPS FPGA images, their DMA accesses
must go via Master Security Controllers. Switch the
PL080/PL081 model to take a MemoryRegion property which
defines its downstream for making DMA accesses.

Since the PL08x are only used in two board models, we
make provision of the 'downstream' link mandatory and convert
both users at once, rather than having it be optional with
a default to the system address space.

6d0ed6ba6c hw/dma/pl080: Support all three interrupt lines
The PL080 and PL081 have three outgoing interrupt lines:
 * DMACINTERR signals DMA errors
 * DMACINTTC is the DMA count interrupt
 * DMACINTR is a combined interrupt, the logical OR of the other two

We currently only implement DMACINTR, because that's all the
realview and versatile boards needed, but the instances of the
PL081 in the MPS2 firmware images use all three interrupt lines.
Implement the missing DMACINTERR and DMACINTTC.

If an instruction is conditional (like CBZ) and it is executed
conditionally (using the ITx instruction), a jump to an undefined

CBZ in IT block is an UNPREDICTABLE behavior, but we should not
crash.  Honouring the condition code is allowed by the spec in this
case (constrained unpredictable, ARMv8, section K1.1.7), and matches
what we do for other "UNPREDICTABLE inside an IT block" instructions.

does not already exist.  Previously multiple labels were created, but
