Instead of using helper_unaligned_{ld,st}, use the full load/store helpers.
This will allow the fast path to increase alignment to implement atomicity

Always reserve r3 for tlb softmmu lookup. Fix a bug in user-only
ALL_QLDST_REGS, in that r14 is clobbered by the BLNE that leads
to the misaligned trap. Remove r0+r1 from user-only ALL_QLDST_REGS;
I believe these had been reserved for bswap, which we no longer
perform during qemu_st.

This field may be used to describe the precise atomicity requirements
of the guest, which may then be used to constrain the methods by which
it may be emulated by the host.
For instance, the AArch64 LDP (32-bit) instruction changes semantics
with ARMv8.4 LSE2, from
MO_64 | MO_ATOM_IFALIGN_PAIR
(64-bits, single-copy atomic only on 4 byte units,
nonatomic if not aligned by 4),
to
MO_64 | MO_ATOM_WITHIN16
(64-bits, single-copy atomic within a 16 byte block)
The former may be implemented with two 4 byte loads, or a single 8 byte
load if that happens to be efficient on the host. The latter may not
be implemented with two 4 byte loads and may also require a helper when
misaligned.

obvious conflicts between packages that are being added and those that are

Kernel commit 292a7d6fca33 ("KVM: s390: pv: fix asynchronous teardown
for small VMs") causes the KVM_PV_ASYNC_CLEANUP_PREPARE ioctl to fail
if the VM is not larger than 2GiB. QEMU would attempt it and fail,
print an error message, and then proceed with a normal teardown.
Avoid attempting to use asynchronous teardown altogether when the VM is
not larger than 2 GiB. This will avoid triggering the error message and
also avoid pointless overhead; normal teardown is fast enough for small
VMs.

Bios bits avocado tests need mformat (provided by the mtools package) and
xorriso tools in order to run within gitlab CI containers. Add those
dependencies within the Dockerfiles so that containers can be built with
those tools present and bios bits avocado tests can be run there.
xorriso package conflicts with genisoimage package on some distributions.
Therefore, it is not possible to have both the packages at the same time
in the container image uniformly for all distribution flavors. Further,
on some distributions like RHEL, both xorriso and genisoimage
packages provide /usr/bin/genisoimage and on some other distributions like
Fedora, only genisoimage package provides the same utility.
Therefore, this change removes the dependency on geninsoimage for building
container images altogether keeping only xorriso package. At the same time,
cdrom-test.c is updated to use and check for existence of only xorrisofs.

By default, Windows doesn't allow to create soft links for user account
and only administrator is allowed to do this. To fix this problem you have
to raise your permissions or enable Developer Mode, which available since
Windows 10. Additional explanation when build fails will allow developer
to fix the problem on his computer faster.

PCIBridge
The lifetime of the PCIBridgeWindows instance accessed via the windows pointer
in struct PCIBridge is managed separately from the PCIBridge itself.
Triggered by ./qemu-system-x86_64 -M x-remote -display none -monitor stdio
QEMU monitor: device_add cxl-downstream
In some error handling paths (such as the above due to attaching a cxl-downstream
port anything other than a cxl-upstream port) the g_free() of the PCIBridge
windows in pci_bridge_region_cleanup() is called before the final call of
flatview_uref() in address_space_set_flatview() ultimately from
drain_call_rcu()
At one stage this resulted in a crash, currently can still be observed using
valgrind which records a use after free.
When present, only one instance is allocated. pci_bridge_update_mappings()
can operate directly on an instance rather than creating a new one and
swapping it in. Thus there appears to be no reason to not directly
couple the lifetimes of the two structures by embedding the PCIBridgeWindows
within the PCIBridge removing the need for the problematic separate free.
Patch is same as was posted deep in the discussion.

The qmp_discard_response method simply ignores the result of the QMP
command, merely unref'ing the object. This is a bad idea for tests
as it leaves no trace if the QMP command unexpectedly failed. The
qtest_qmp_assert_success method will validate that the QMP command
returned without error, and if errors occur, it will print a message
on the console aiding debugging.

We can have failure with the inet type test because the port address
is not allocated atomically and can be taken by another test between its
selection and the start of QEMU. To avoid that, use an unix socket with
a path that is unique
