78d6c4c33d hw/core/cpu: removed cpu_dump_statistics function 
No more architectures set the pointer to dump_statistics, so there's no
point in keeping it, or the related cpu_dump_statistics function.

65c57115df cpu: Directly use get_memory_mapping() fallback handlers in place 
No code uses CPUClass::get_memory_mapping() outside of hw/core/cpu.c:

  $ git grep -F -- '->get_memory_mapping'
  hw/core/cpu.c:87:    cc->get_memory_mapping(cpu, list, errp);
  hw/core/cpu.c:439:    k->get_memory_mapping = cpu_common_get_memory_mapping;
  target/i386/cpu.c:7422:    cc->get_memory_mapping = x86_cpu_get_memory_mapping;

Check the handler presence in place and remove the common fallback code.

cdba7e2f49 cpu: Introduce cpu_virtio_is_big_endian() 
Introduce the cpu_virtio_is_big_endian() generic helper to avoid
calling CPUClass internal virtio_is_big_endian() one.

Similarly to commit bf7663c4bd ("cpu: introduce
CPUClass::virtio_is_big_endian()"), we keep 'virtio' in the method
name to hint this handler shouldn't be called anywhere but from the
virtio code.

df4fd7d5c8 cpu: Split as cpu-common / cpu-sysemu 
The current cpu.c contains sysemu-specific methods.
To avoid building them in user-mode builds, split the
current cpu.c as cpu-common.c / cpu-sysemu.c.

Start by moving cpu_get_crash_info().
