Richard Henderson ab409bb3fe target-m68k: Use cpu_exec_interrupt qom hook
Since do_interrupt_m68k_hardirq is no longer used outside
op_helper.c, make it static.

Andreas Färber 00b941e581 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().

Prepares for changing cpu_memory_rw_debug() argument to CPUState.

Andreas Färber 6e42be7cd1 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
break, too.

This should slightly improve interrupt etc. performance when going from
CPUFooState to FooCPU.
For any additional CPU() casts see 3556c233d9
(qom: allow turning cast debugging off).

Make cpustats monitor command available unconditionally.

Prepares for changing kvm_handle_internal_error() and kvm_cpu_exec()

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 fadf982584 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.

Andreas Färber 6d1bbc6273 target-m68k: Introduce QOM realizefn for M68kCPU
Introduce realizefn and set realized = true in cpu_m68k_init().

Split off GDB registration to a new m68k_cpu_init_gdb() so that it can
be called from the realizefn.
