d32bd032d8 ("s390x/ccw: create s390 phb conditionally") made
registering the s390 pci host bridge conditional on presense
of the zpci facility bit. Sadly, that breaks migration from
machines that did not use the cpu model (2.7 and previous).
Create the s390 phb for pre-cpu model machines as well: We can
tweak s390_has_feat() to always indicate the zpci facility bit
when no cpu model is available (on 2.7 and previous compat machines).

Some time ago we discussed that using "id" as property name is not the
right thing to do, as it is a reserved property for other devices and
will not work with device_add.
Switch to the term "core-id" instead, and use it as an equivalent to
"CPU address" mentioned in the PoP. There is no such thing as cpu number,
so rename env.cpu_num to env.core_id. We use "core-id" as this is the
common term to use for device_add later on (x86 and ppc).
We can get rid of cpu->id now. Keep cpu_index and env->core_id in sync.
cpu_index was already implicitly used by e.g. cpu_exists(), so keeping
both in sync seems to be the right thing to do.
cpu_index will now no longer automatically get set via
cpu_exec_realizefn(). For now, we were lucky that both implicitly stayed
in sync.
Our new cpu property "core-id" can be a static property. Range checks can
be avoided by using the correct type and the "setting after realized"
check is done implicitly.
device_add will later need the reserved "id" property. Hotplugging a CPU
on s390x will then be: "device_add host-s390-cpu,id=cpu2,core-id=2".

There are certain features that we put into base models, but that are
not relevant for the actual search. The most famous example are
MSA subfunctions that might be disabled on certain real hardware out
there.
While the kvm host model detection will usually detect the correct model
on such machines (as it will in the common case not pass features to check
for into s390_find_cpu_def()), baselining will fall back to a quite old
model just because some MSA subfunctions are missing.
Let's improve that by ignoring lack of these features while performing
the search for a base model.

The SIE_KSS feature will allow a guest to use KSS for a nested guest.
To create a nested guest the SIE_F2 facility is still necessary.
Since SIE_F2 is not part of the default model it does not make

STFL bit 4 and 5 are just indications to the guest, which TLB entries an
IDTE call will clear. These are performance indicators for the guest.
STFL bit 4:
INVALIDATE DAT TABLE ENTRY (IDTE) performs
the invalidation-and-clearing operation by
selectively clearing TLB segment-table entries
when a segment-table entry or entries are
invalidated. IDTE also performs the clearing-by-
ASCE operation. Unless bit 4 is one, IDTE simply
purges all TLBs. Bit 3 is one if bit 4 is one.
We can simply set STFL bit 4 ("idtes") and still purge the complete TLB.
Purging more than advertised is never bad. E.g. Linux doesn't even care
about this bit. We can optimized this later.
This is helpful, as the z9 base model contains this facility.
STFL bit 5 (clearing TLB region-table-entries) was never implemented on
real HW, therefore we can simply ignore it for now.

The response for query-cpu-definitions didn't include the
unavailable-features field, which is used by libvirt to figure
out whether a certain cpu model is usable on the host.
The unavailable features are now computed by obtaining the host CPU
model and comparing it against the known CPU models. The comparison
takes into account the generation, the GA level and the feature
bitmaps. In the case of a CPU generation/GA level mismatch
a feature called "type" is reported to be missing.
As a result, the output of virsh domcapabilities would change
from something like
...

A specification exception will be injected if the address is not aligned

Currently we only present the plain z900 feature bits to the guest,
but QEMU already emulates some additional features (but not all of
the next CPU generation, so we can not use the next CPU level as
default yet). Since newer Linux kernels are checking the feature bits
and refuse to work if a required feature is missing, it would be nice
to have a way to present more of the supported features when we are
running with the "qemu" CPU.
This patch now adds the supported features to the "full_feat" bitmap,
so that additional features can be enabled on the command line now,
for example with:
qemu-system-s390x -cpu qemu,stfle=true,ldisp=true,eimm=true,stckf=true

Currently, under z/VM on a 0x2827, QEMU will detect a 0x2828 if no
IBC value is provided. QEMU will simply take the last model of that HW
generation, which happens to be the BC version.
Let's improve our search for that case by selecting the latest CPU
definition that matches the CPU type. This for example will avoid
detecting an z13 as a z13s.
We might still detect a GA2 version on a GA1 system, but as we don't
have further information at hand, there isn't too much we can do about
it. The alternative of always presenting the oldest GA is not backward
compatible, e.g:
You're running on 0x2827 GA2.
Old QEMU version indicated "0x2828 GA1 == 0x2827 GA2". After you updated
QEMU, you suddenly detect "0x2827 GA1". You're previous libvirt guest
might suddenly refuse to run.
In the end presenting a newer GA level does not matter because:
1: All GAX models share the same base feature set. A GAX++ might
support "more features".
2: Without an IBC, the guest can't detect the GA version.
If we have no IBC (esp. unblocked_ibc == 0), the IBC we will present
to the guest in read_SCP_info() will be 0. The guest will not know
which GA version it has. The problem of missing IBC propagates.
If we don't have a feature of the GA++ version, also our guest won't
have it. So in summary, the guest also has no idea of its GA version.

An upcoming Coccinelle cleanup script wanted to reformat the casts
present in this file - but on closer look, we don't need the casts
at all because C automatically converts void* to any other pointer.

The split between tests/test-qobject-input-visitor.c and
tests/test-qobject-input-strict.c now makes less sense than ever. The
next commit will take care of that.

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
