Markus Armbruster a27bd6c779 Include hw/qdev-properties.h less
In my "build everything" tree, changing hw/qdev-properties.h triggers
a recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h.  Include hw/qdev-core.h there
instead.

hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

While there, delete a few superfluous inclusions of hw/qdev-core.h.

Touching hw/qdev-properties.h now recompiles some 1200 objects.

Markus Armbruster bbfff19688 Clean up includes
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes, with the changes

    tests/test-rcu-simpleq.c
    tests/test-rcu-tailq.c
    tests/uefi-test-tools/UefiTestToolsPkg/BiosTablesTest/BiosTablesTest.c

We're in the process of spinning out slirp/.  tests/fp/platform.h is
has to include qemu/osdep.h because tests/fp/berkeley-softfloat-3/ and
tests/fp/berkeley-testfloat-3/ don't.  tests/uefi-test-tools/ is guest
software.  The remaining reverts are the same as in commit
b7d89466dd.

Peter Maydell 7ea7b9ad53 qom/cpu: Add cluster_index to CPUState
For TCG we want to distinguish which cluster a CPU is in, and
we need to do it quickly. Cache the cluster index in the CPUState
struct, by having the cluster object set cpu->cluster_index for
each CPU child when it is realized.

This means that board/SoC code must add all CPUs to the cluster
before realizing the cluster object. Regrettably QOM provides no
way to prevent adding children to a realized object and no way for
the parent to be notified when a new child is added to it, so
we don't have any way to enforce/assert this constraint; all
we can do is document it in a comment. We can at least put in a
check that the cluster contains at least one CPU, which should
catch the typical cases of "realized cluster too early" or
"forgot to parent the CPUs into it".

The restriction on how many clusters can exist in the system
is imposed by TCG code which will be added in a subsequent commit,
but the check to enforce it in cluster.c fits better in this one.

Luc Michel 335d52f457 hw/cpu: introduce CPU clusters
This commit adds the cpu-cluster type. It aims at gathering CPUs from
the same cluster in a machine.

For now it only has a `cluster-id` property.

Peter Krempa 27393c33d8 qapi: keep names in 'CpuInstanceProperties' in sync with struct CPUCore
struct CPUCore uses 'id' suffix in the property name. As docs for
query-hotpluggable-cpus state that the cpu core properties should be
passed back to device_add by management in case new members are added
and thus the names for the fields should be kept in sync.
