cpu: Drop cpu_model_str from CPU_COMMON

Since this is only read in cpu_copy() and linux-user has a global
cpu_model, drop the field from generic code.

cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"

Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code.
This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed".

The reason for the failure is that CPUClass::kvm_fd is not yet...

cpu: Introduce CPUState::gdb_num_regs and CPUClass::gdb_num_core_regs

CPUState::gdb_num_regs replaces num_g_regs.
CPUClass::gdb_num_core_regs replaces NUM_CORE_REGS.

Allows building gdb_register_coprocessor() for xtensa, too.

As a side effect this should fix coprocessor register numbering for SMP....

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: Introduce CPUClass::synchronize_from_tb() for cpu_pc_from_tb()

Where no extra implementation is needed, fall back to CPUClass::set_pc().

cpu: Introduce CPUClass::set_pc() for gdb_set_cpu_pc()

This moves setting the Program Counter from gdbstub into target code.
Use vaddr type as upper-bound replacement for target_ulong.

log: Change log_cpu_state[_mask]() argument to CPUState

Since commit 878096eeb278a8ac1ccd6667af73e026f29b4cf5 (cpu: Turn
cpu_dump_{state,statistics}() into CPUState hooks) CPUArchState is no
longer needed.

Add documentation and make the functions available through qemu/log.h...

cpu: Move reset logging to CPUState

x86 was using additional CPU_DUMP_* flags, so make that configurable in

This adds reset logging for alpha, unicore32 and xtensa.

cpu: Change qemu_init_vcpu() argument to CPUState

This allows to move the call into CPUState's realizefn.
Therefore move the stub into libqemustub.a.

arguments to CPUState.

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-sh4: Introduce SuperHCPU subclasses

Store legacy name in SuperHCPUClass for -cpu ? and for case-insensitive
class lookup.

List CPUs by iterating over TYPE_SUPERH_CPU subclasses.

target-sh4: Move PVR/PRR/CVR into SuperHCPUClass

They are never changed once initialized, and moving them to the class
will allow to inspect them before instantiating.

cpu: Add CPUArchState pointer to CPUState

The target-specific ENV_GET_CPU() macros have allowed us to navigate
from CPUArchState to CPUState. The reverse direction was not supported.
Avoid introducing CPU_GET_ENV() macros by initializing an untyped
pointer that is initialized in derived instance_init functions....

cpu: Move cpu_index field to CPUState

Note that target-alpha accesses this field from TCG, now using a
negative offset. Therefore the field is placed last in CPUState.

Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change.
