ppc: Fix up usermode only builds

The recent usage of MemoryRegion in kvm_ppc.h breaks builds with
CONFIG_USER_ONLY=y. This patch fixes it.

KVM: PPC: Override host vmx/vsx/dfp only when information known

The -cpu host feature tries to find out the host capabilities based
on device tree information. However, we don't always have that available
because it's an optional property in dt.

So instead of force unsetting values depending on an unreliable source...

PPC: Disable non-440 CPUs for ppcemb target

The sole reason we have the ppcemb target is to support MMUs that have
less than the usual 4k possible page size. There are very few of these
chips and I don't want to add additional QA and testing burden to everyone...

pseries: Correct vmx/dfp handling in both KVM and TCG cases

Currently, when KVM is enabled, the pseries machine checks if the host
CPU supports VMX, VSX and/or DFP instructions and advertises
accordingly in the guest device tree. It does this regardless of what...

PPC: Bump qemu-system-ppc to 64-bit physical address space

Some 32-bit PPC CPUs can use up to 36 bit of physical address space.
Treat them accordingly in the qemu-system-ppc binary type.

ppc: Remove broken partial PVR matching

The ppc target contains a ppc_find_by_pvr() function, which looks up a
CPU spec based on a PVR (that is, based on the value in the target cpu's
Processor Version Register). PVR values contain information on both the...

ppc: First cut implementation of -cpu host

For convenience with kvm, x86 allows the user to specify -cpu host on the
qemu command line, which means make the guest cpu the same as the host
cpu. This patch implements the same option for ppc targets.

For now, this just read the host PVR (Processor Version Register) and...

ppc: Add cpu defs for POWER7 revisions 2.1 and 2.3

This patch adds cpu specs to the table for POWER7 revisions 2.1 and 2.3.
This allows -cpu host to be used on these host cpus.

ppc: Generalize the kvmppc_get_clockfreq() function

Currently the kvmppc_get_clockfreq() function reads the host's clock
frequency from /proc/device-tree, which is useful to past to the guest
in KVM setups. However, there are some other host properties
advertised in the device tree which can also be relevant to the...

pseries: Add device tree properties for VMX/VSX and DFP under kvm

Sufficiently recent PAPR specifications define properties "ibm,vmx"
and "ibm,dfp" on the CPU node which advertise whether the VMX vector
extensions (or the later VSX version) and/or the Decimal Floating...
