Andreas Färber 97a8ea5a3a cpu: Replace do_interrupt() by CPUClass::do_interrupt method
This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU
families.

Andreas Färber 259186a7d2 cpu: Move halted and interrupt_request fields to CPUState
Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

Pass PowerPCCPU to kvmppc_handle_halt().

Andreas Färber e9a9607527 target-ppc: Move CPU aliases out of translate_init.c
Move array of CPU aliases to cpu-models.c, alongside model definitions.
This requires to zero-terminate the aliases array since ARRAY_SIZE() can
no longer be used in translate_init.c then.

Andreas Färber 35e21d3f53 target-ppc: Report CPU aliases for QMP
The QMP query-cpu-definitions implementation iterated over CPU classes
only, which were getting less and less as aliases were extracted.

Keep them in QMP as valid -cpu arguments even if not guaranteed stable.

Andreas Färber 5ba4576b85 target-ppc: Make host CPU a subclass of the host's CPU model
This avoids assigning individual class fields and contributors
forgetting to add field assignments in KVM-only code.

ppc_cpu_class_find_by_pvr() requires the CPU model classes to be
registered, so defer host CPU type registration to kvm_arch_init().

Only register the host CPU type if there is a class with matching PVR.
This lets us drop error handling from instance_init.

David Gibson 70b79849b8 target-ppc: Synchronize FPU state with KVM
Currently qemu does not get and put the state of the floating point and
vector registers to KVM.  This is obviously a problem for savevm, as well
as possibly being problematic for debugging of FP-using guests.

This patch fixes this by using new extensions to the ONE_REG interface to
synchronize the qemu floating point state with KVM.

David Gibson d67d40ea07 target-ppc: Add mechanism for synchronizing SPRs with KVM
Currently when runing under KVM on ppc, we synchronize a certain number of
vital SPRs to KVM through the SET_SREGS call.  This leaves out quite a lot
of important SPRs which are maintained in KVM.  It would be helpful to
have their contents in qemu for debugging purposes, and when we implement
migration it will be vital, since they include important guest state that
will need to be restored on the target.

This patch sets up for synchronization of any registers supported by the
KVM ONE_REG calls.  A new variant on spr_register() allows a ONE_REG id to
be stored with the SPR information.  When we set/get information to KVM
we also synchronize any SPRs so registered.

For now we set this mechanism up to synchronize a handful of important
registers that already have ONE_REG IDs, notably the DAR and DSISR.

Andreas Färber 4d7fb187e0 target-ppc: Register all types for TARGET_PPCEMB
Don't attempt to suppress registration of CPU types, since the criteria
is actually a property of the class and should thus become a field.
Since we can't check a field set in a class_init function before
registering the type that leads to execution of that function, guard the
-cpu class lookup instead and suppress exposing these classes in -cpu ?
and in QMP.

In case someone tries to hot-add an incompatible CPU via device_add,
error out in realize.

Turn the array of model definitions into a set of self-registering QOM
types with their own class_init. Unique identifiers are obtained from
the combination of PVR, SVR and family identifiers; this requires all

left after this commit that are not currently being compiled.
