The pipeline UI will truncate the names of jobs after about 15
characters. As a result with the cross-builds, we truncate the
most important part of the job name. Putting the most important
part first is robust against truncation, and we can drop the
redundant "-cross" stub.

Currently we have nine different cross build jobs, but as we introduce
more native jobs this is going to result in a very long CI execution
time. For developers testing their personal branches under development
it is generally sufficient to just look at a couple of interesting
scenarios, namely 32-bit and big endian.
This splits the cross build jobs so that by default only the armv7
and s390x archs are built. The remainining archs are setup so that they
are only built for code on the master branch, which will have the effect
of doing post-merge testing. Developers can opt-in to full testing of
their pre-merge code by pushing it to a branch with a name prefix of
"ci-full-".

One of the mitigation methods for TAA[1] is to disable TSX
support on the host system. Linux added a mechanism to disable
TSX globally through the kernel command line, and many Linux
distributions now default to tsx=off. This makes existing CPU
models that have HLE and RTM enabled not usable anymore.
Add new versions of all CPU models that have the HLE and RTM
features enabled, that can be used when TSX is disabled in the
host system.
On systems disabling the features without those types defined
in cpu-maps users end up without modern CPU types in the list
of usable CPUs to use in the likes of virsh domcapabilities
or tools higher in the stack like virt-manager.

The PMU feature is enabled by default in ppc64 guests and can't
be disabled via Libvirt or QEMU [1]. The current PMU feature
implementation does not allow PMU to enabled or disabled in the
ppc64 guest. Declaring the PMU feature will make the 'pmu'
property to be passed on to QEMU, but this property isn't
available for ppc64:
qemu-kvm: can't apply global host-powerpc64-cpu.pmu=on: Property '.pmu' not found
A similar error is thrown when trying to disable the PMU.
This patch standardizes the PMU handling for ppc64 guests by:
- throwing an error if the user attempts to set the feature to
'off', given that this feature can't be turned off at all;
- allowing the feature to be declared as 'on' in the domain XML.
This is done by skipping ppc64 guests when creating the command
line for this feature.

Hyperv features are supported by both x86 and aarch64. The <hyperv/>
declaration in the XML by itself is benign to other architectures,
but any of its 14 current features will break QEMU with an error
like this (from ppc64):
qemu-kvm: Expected key=value format, found hv_relaxed
This is a more extreme case than the one for apic eoi because we
would need an extra 'switch' statement, with all current Hyperv
features in the body of qemuDomainDefValidateFeatures(), to
check if the user attempted to activate any of them. It's easier to
simply fail to launch with any 'hyperv' declaration in the XML for
every arch which is not x86 and aarch64.
A fair disclaimer about Windows and PowerPC: the last Windows version
that ran in the architecture is the hall of famer Windows NT 4.0,
launched in 1996 and with end of extended support for the Server
version in 2004 [1]. I am acknowledging that there might be Windows
NT 4.0 users running in PowerPC, but not enough people running it
under KVM/QEMU to justify Libvirt allowing 'hyperv' to exist in the
domain XML of ppc64 domains.

The 'pvspinlock' feature is x86 only. The "<pvspinlock/>" declaration
will always have a value 'on' or 'off', and both will break QEMU when
launching non-x86 guests. This is the error message for
"<pvspinlock state='on'/>" when running a ppc64 guest:
qemu-kvm: Expected key=value format, found +kvm_pv_unhalt
A similar error message is thrown for "<pvspinlock state='off'/>".
This patch prevents non-x86 guests from launching with any
pvspinlock setting with a more informative error message:
error: unsupported configuration: The 'pvspinlock' feature is not

The "<apic/>" feature, although it's available only for x86 guests,
can be declared in the domain XML of other archs without errors.
But setting its 'eoi' attribute will break QEMU. For "<apic eoi='on'/>",
in a ppc64 guest:
qemu-kvm: Expected key=value format, found +kvm_pv_eoi
A similar error happens with eoi='off'.
One can argue that it's better to simply forbid launching non-x86
guests with "<apic/>" declared in the XML - it is a feature that
the architecture doesn't support and this would make it clearer
about it. This is sensible, but there are non-x86 guests that are
running with "<apic/>" declared in the domain (and A LOT of guests
running with "<acpi/>" for that matter, probably reminiscent of x86
templates that were reused for other archs) that will stop working if we
go this route.
A more subtle approach is to detect if the 'eoi' element is being set
for non-x86 guests and warn the user about it with a better error
message than the one QEMU provides. This is the new error message
when any value is set for the 'eoi' element in a ppc64 XML:
error: unsupported configuration: The 'eoi' attribute of the 'apic'
feature is not supported for architecture 'ppc64' or machine type
'pseries'.

This fixes processes being leaked, as they are not killed in
