This series adds a new PA-RISC machine emulation for the HP-PARISC
C3700 workstation.
The physical HP C3700 machine has a PA2.0 (64-bit) CPU, in contrast to
the existing emulation of a B160L workstation which is a 32-bit only
machine and where it's Dino PCI controller isn't 64-bit capable.
With the HP C3700 machine emulation (together with the emulated Astro
Memory controller and the Elroy PCI bridge) it's now possible to
enhance the hppa CPU emulation to support the 64-bit instruction set
in upcoming patches.

The modification of the CPU attributes are done through a monitor
command.
It allows to move the core inside the topology tree to optimize
the cache usage in the case the host's hypervisor previously
moved the CPU.
The same command allows to modify the CPU attributes modifiers
like polarization entitlement and the dedicated attribute to notify
the guest if the host admin modified scheduling or dedication of a vCPU.
With this knowledge the guest has the possibility to optimize the
usage of the vCPUs.
The command has a feature unstable for the moment.

When the host supports the CPU topology facility, the PTF
instruction with function code 2 is interpreted by the SIE,
provided that the userland hypervisor activates the interpretation
by using the KVM_CAP_S390_CPU_TOPOLOGY KVM extension.
The PTF instructions with function code 0 and 1 are intercepted
and must be emulated by the userland hypervisor.
During RESET all CPU of the configuration are placed in

The topology information are attributes of the CPU and are
specified during the CPU device creation.
On hot plug we:
- calculate the default values for the topology for drawers,
books and sockets in the case they are not specified.
- verify the CPU attributes
- check that we have still room on the desired socket
The possibility to insert a CPU in a mask is dependent on the
number of cores allowed in a socket, a book or a drawer, the
checking is done during the hot plug of the CPU to have an
immediate answer.
If the complete topology is not specified, the core is added
in the physical topology based on its core ID and it gets
defaults values for the modifier attributes.
This way, starting QEMU without specifying the topology can
still get some advantage of the CPU topology.
