A few of the new instructions added inadvertently changed the type of
old instruction(PPC_ALTIVEC) to PPC2_ALTIVEC_207 in the dual form
declaration.

commit: b5d569a1 (target-ppc: add vector extract instructions)
commit: e7b1e06f (target-ppc: add vector insert instructions)
commit: 3aa56a19 (target-ppc: add vector compare not equal instructions)

New ISA 3.0 instructions added:
    vextractub     PPC_NONE     PPC2_ISA300
    vextractuh     PPC_NONE     PPC2_ISA300
    vextractuw     PPC_NONE     PPC2_ISA300
    vinsertb       PPC_NONE     PPC2_ISA300

    vinsertw       PPC_NONE     PPC2_ISA300

    vcmpneh        PPC_NONE     PPC2_ISA300
    vcmpnew        PPC_NONE     PPC2_ISA300

Affected older instructions:
    vspltb         PPC_ALTIVEC  PPC_NONE
    vsplth         PPC_ALTIVEC  PPC_NONE
    vspltw         PPC_ALTIVEC  PPC_NONE

    vcmpequh       PPC_ALTIVEC  PPC_NONE
    vcmpequw       PPC_ALTIVEC  PPC_NONE

Change the instruction type/type2 for the older instructions back to
what it was(PPC_ALTIVEC).

KVM-PR currently does not support transactional memory, and the
implementation in TCG is just a fake. We should not announce TM
support in the ibm,pa-features property when running on such a

implementation supports it (i.e. recent versions of KVM-HV).

The current code uses pa_features_206 for POWERPC_MMU_2_06, and
for everything else, it uses pa_features_207. This is bad in some
cases because there is also a "degraded" MMU version of ISA 2.06,
called POWERPC_MMU_2_06a, which should of course use the flags for
2.06 instead. And there is also the possibility that the user runs
the pseries machine with a POWER5+ or even 970 processor. In that
case we certainly do not want to set the flags for 2.07, and rather
simply skip the setting of the pa-features property instead.

In the ARM v6 architecture, 'sub pc, pc, 1' is not an interworking
branch, so the computed new value is written to r15 as a normal
value. The architecture says that in this case, bits [1:0] of
the value written must be ignored if we are in ARM mode (or
bit [0] ignored if in Thumb mode); this is a change from the
ARMv4/v5 specification that behaviour is UNPREDICTABLE.
Use the correct mask on the PC value when doing a non-interworking
store to PC.

A popular library used on RaspberryPi uses this instruction
as part of a trick to determine whether it is running on
ARMv6 or ARMv7, and we were mishandling the sequence.

Add a generic loader to QEMU which can be used to load images or set
memory values.

Internally inside QEMU this is a device. It is a strange device that
provides no hardware interface but allows QEMU to monkey patch memory
specified when it is created. To be able to do this it has a reset
callback that does the memory operations.

This device allows the user to monkey patch memory. To be able to do
this it needs a backend to manage the datas, the same as other
memory-related devices. In this case as the backend is so trivial we
have merged it with the frontend instead of creating and maintaining a
seperate backend.

The ITS control frame is in-kernel emulated while accesses to the
GITS_TRANSLATER are mediated through the KVM_SIGNAL_MSI ioctl (MSI
direct MSI injection advertised by the CAP_SIGNAL_MSI capability)

the kvm_gsi_direct_mapping is explicitly set to false to emphasize the
difference with GICv2M. Direct mapping cannot work with ITS since
the content of the MSI data is not the target interrupt ID but an
eventd id.

GSI routing is advertised (kvm_gsi_routing_allowed) as well as
msi/irqfd signaling (kvm_msi_via_irqfd_allowed).

The MSI frame (GITS_TRANSLATER) absolute GPA is computed on first
kvm_its_send_msi() call. It is then passed through KVM_SIGNAL_MSI

This is the basic skeleton for both KVM and software-emulated ITS.
Since we already prepare status structure, we also introduce complete
VMState description. But, because we currently have no migratable
implementations, we also set unmigratable flag.

Advertise gsi routing and set up irqchip routing entries for
GIC SPIs.

This is not mandated as long as MSI routing is not used
(because the kernel sets a default irqchip routing table).
However once MSI routing gets used (for VIRTIO-PCI vhost for
example), the first call to KVM_SET_GSI_ROUTING overrides the
kernel default irqchip table.

If no routing entry exists for the GSI, any IRQFD signaling for
this GSI will fail.
