powerpc: add PVR mask support

IBM POWERPC processors encode PVR as a CPU family in higher 16 bits and
a CPU version in lower 16 bits. Since there is no significant change
in behavior between versions, there is no point to add every single CPU
version in QEMU's CPU list. Also, new CPU versions of already supported...

target-ppc: dump-guest-memory support

This patch add support for dumping guest memory using dump-guest-memory
monitor command.

Before patch:

(qemu) dump-guest-memory testcrash
this feature or command is not currently supported

target-ppc: Convert ppc cpu savevm to VMStateDescription

The savevm code for the powerpc cpu emulation is currently based around
the old register_savevm() rather than register_vmstate() method. It's also
rather broken, missing some important state on some CPU models....

cpu: Introduce CPUClass::gdb_{read,write}_register()

Completes migration of target-specific code to new target-*/gdbstub.c.

cpu: Turn cpu_get_phys_page_debug() into a CPUClass hook

Change breakpoint_invalidate() argument to CPUState alongside.

Since all targets now assign a softmmu-only field, we can drop helpers
cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd()....

cpu: Drop unnecessary dynamic casts in *_env_get_cpu()

A transition from CPUFooState to FooCPU can be considered safe,
just like FooCPU::env access in the opposite direction.
The only benefit of the FOO_CPU() casts would be protection against
bogus CPUFooState pointers, but then surrounding code would likely...

cpu: Turn cpu_dump_{state,statistics}() into CPUState hooks

Make cpustats monitor command available unconditionally.

Prepares for changing kvm_handle_internal_error() and kvm_cpu_exec()
arguments to CPUState.

pseries: Fixes and enhancements to L1 cache properties

PAPR requires that the device tree's CPU nodes have several properties
with information about the L1 cache. We already create two of these
properties, but with incorrect names - "[id]cache-block-size" instead...

target-ppc: Use QOM method dispatch for MMU fault handling

After previous cleanups, the many scattered checks of env->mmu_model in
the ppc MMU implementation have, at least for "classic" hash MMUs been
reduced (almost) to a single switch at the top of
cpu_ppc_handle_mmu_fault()....

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...

target-ppc: Convert CPU definitions

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
alias #defines to be removed from the list. Possibly there are some more...

cpu: Introduce ENV_OFFSET macros

Introduce ENV_OFFSET macros which can be used in non-target-specific
code that needs to generate TCG instructions which reference CPUState
fields given the cpu_env register that TCG targets set up with a
pointer to the CPUArchState struct....

target-ppc: Update PowerPCCPU to QOM realizefn

realized = true in cpu_ppc_init().

target-ppc: Slim conversion of model definitions to QOM subclasses

Since the model list is highly macrofied, keep ppc_def_t for now and
save a pointer to it in PowerPCCPUClass. This results in a flat list of
subclasses including aliases, to be refined later....

target-ppc: QOM'ify CPU

Embed CPUPPCState as first member of PowerPCCPU.
Distinguish between "powerpc-cpu", "powerpc64-cpu" and
"embedded-powerpc-cpu".

Let CPUClass::reset() call cpu_state_reset() for now.
