The zPCI group and function structures are big endian. However, we do
not consistently store them as big endian locally, and are missing some
conversions.
Let's just store the structures as host endian instead and convert to
big endian when actually handling the instructions retrieving the data.
Also fix the layout of ClpReqQueryPciGrp: g is actually only 8 bit. This
also fixes accesses on little endian hosts, and makes accesses on big
endian hosts consistent.

Hot-unplugging a vfio-pci device on s390x causes a QEMU crash:
qemu-system-s390x: ../softmmu/memory.c:2772:
do_address_space_destroy: Assertion `QTAILQ_EMPTY(&as->listeners)' failed.
In s390, the IOMMU address space is freed during device unplug but the
associated vfio-pci device may not yet be finalized and therefore may
still have a listener registered to the IOMMU address space.
Commit a2166410ad ("spapr_pci: Unregister listeners before destroying

We are now seeing this in s390x; it would seem the possibility for this
issue was already present but based on a bisect commit 2d24a64661
("device-core: use RCU for list of children of a bus") has now changed
the timing such that it is now readily reproducible.

This causes a warning with clang 11 or greater, which checks that

In this case, however, the warning is a false positive, because
IPLBlockPV and IplBlockFcp are allocated in a union wrapped at 4K,
making the union non-variable sized.
Fix the warning by turning the two variable sized arrays into arrays

DIAGNOSE 0x318 (diag318) is an s390 instruction that allows the storage
of diagnostic information that is collected by the firmware in the case
of hardware/firmware service events.
QEMU handles the instruction by storing the info in the CPU state. A
subsequent register sync will communicate the data to the hypervisor.
QEMU handles the migration via a VM State Description.
This feature depends on the Extended-Length SCCB (els) feature. If
els is not present, then a warning will be printed and the SCLP bit
that allows the Linux kernel to execute the instruction will not be
set.
Availability of this instruction is determined by byte 134 (aka fac134)
bit 0 of the SCLP Read Info block. This coincidentally expands into the
space used for CPU entries, which means VMs running with the diag318
capability may not be able to read information regarding all CPUs
unless the guest kernel supports an extended-length SCCB.
This feature is not supported in protected virtualization mode.

As more features and facilities are added to the Read SCP Info (RSCPI)
response, more space is required to store them. The space used to store
these new features intrudes on the space originally used to store CPU
entries. This means as more features and facilities are added to the
RSCPI response, less space can be used to store CPU entries.
With the Extended-Length SCCB (ELS) facility, a KVM guest can execute
the RSCPI command and determine if the SCCB is large enough to store a
complete reponse. If it is not large enough, then the required length
will be set in the SCCB header.
The caller of the SCLP command is responsible for creating a
large-enough SCCB to store a complete response. Proper checking should
be in place, and the caller should execute the command once-more with
the large-enough SCCB.
This facility also enables an extended SCCB for the Read CPU Info
(RCPUI) command.
When this facility is enabled, the boundary violation response cannot
be a result from the RSCPI, RSCPI Forced, or RCPUI commands.
In order to tolerate kernels that do not yet have full support for this
feature, a "fixed" offset to the start of the CPU Entries within the
Read SCP Info struct is set to allow for the original 248 max entries
when this feature is disabled.
Additionally, this is introduced as a CPU feature to protect the guest
from migrating to a machine that does not support storing an extended
SCCB. This could otherwise hinder the VM from being able to read all
available CPU entries after migration (such as during re-ipl).

Avoid using atomic_*() names in QEMU's atomic.h since that namespace is

Both VirtioPCIBusClass and VirtioCcwBusClass are typedefs of
VirtioBusClass, but set .class_size in the TypeInfo anyway
to be safe if that changes in the future.

Rename it to be consistent with S390_CCW_MACHINE and
TYPE_S390_CCW_MACHINE.
This will make future conversion to OBJECT_DECLARE* easier.

Each architecture's sourceset is placed in an hw_arch dictionary, and picked up
from there when building the per-emulator static_library.

Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.
