Andreas Färber 91b1df8cf9 cpu: Move reset logging to CPUState
x86 was using additional CPU_DUMP_* flags, so make that configurable in
CPUClass::reset_dump_flags.

This adds reset logging for alpha, unicore32 and xtensa.

Andreas Färber a0762859ae log: Change log_cpu_state[_mask]() argument to CPUState
Since commit 878096eeb2 (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
outside NEED_CPU_H to allow use in qom/cpu.c. Moving them to qom/cpu.h
was not yet possible due to convoluted include paths, so that some
devices grow an implicit and unneeded dependency on qom/cpu.h for now.

Andreas Färber c643bed99f 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.

Andreas Färber 878096eeb2 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.

Andreas Färber b21bfeead2 target-cris: Override do_interrupt for pre-v32 CPU cores
Instead of forwarding from cris_cpu_do_interrupt() to do_interruptv10(),
override CPUClass::do_interrupt with crisv10_cpu_do_interrupt() in the
newly introduced class_init functions.

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 c05efcb18e 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.

The field may not be called "env" due to it being poisoned.

Andreas Färber 6ae064fc67 target-cris: Introduce CRISCPU subclasses
Use class_init functions to initialize the VR in preparation for
overriding v32+ behavior there.

Move cpu_cris_init() to cpu.c and hook up a class_by_name callback.

This change leads to unknown -cpu model names no longer falling back
to a CPU with VR 32 but instead returning NULL.

Andreas Färber d1a94fec3d target-cris: Move TCG initialization to CRISCPU initfn
Split out TCG initialization from cpu_cris_init(). Avoid CPUCRISState
dependency for v10-specific initialization and for non-v10 by inlining
the decision into the initfn as well.

Andreas Färber 55e5c28502 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.

Move common parts of mips cpu_state_reset() to mips_cpu_reset().
