Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: NAndreas Färber <afaerber@suse.de>

Remove the custom qemu_assert() function defined by target-m68k/translate.c in favour of either using glib g_assert_not_reached() (for the genuinely can't-happen cases) or cpu_abort() (for the "this isn't implemented", in line with other unimplemented cases in the target). This has the benefit of silencing some clang warnings about variables used while uninitialized (which are emitted because clang can't figure out that qemu_assert(0, something) never returns.

Adapt the X86CPU implementation to suit the generic hook. This involves a cleanup of error handling to cope with NULL errp. Reviewed-by: NIgor Mammedov <imammedo@redhat.com> Signed-off-by: NAndreas Färber <afaerber@suse.de>

Register separate QOM types for each x86 CPU model. This will allow management code to more easily probe what each CPU model provides, by simply creating objects using the appropriate class name, without having to restart QEMU. This also allows us to eliminate the qdev_prop_set_globals_for_type() hack to set CPU-model-specific global properties. Instead of creating separate class_init functions for each class, I just used class_data to store a pointer to the X86CPUDefinition struct for each CPU model. This should make the patch shorter and easier to review. Later we can gradually convert each X86CPUDefinition field to lists of per-class property defaults. The "host" CPU model is special, as the feature flags depend on KVM being initialized. So it has its own class_init and instance_init function, and feature flags are set on instance_init instead of class_init.

When on KVM mode, enable x2apic by default on all CPU models. Normally we try to keep the CPU model definitions as close as the real CPUs as possible, but x2apic can be emulated by KVM without host CPU support for x2apic, and it improves performance by reducing APIC access overhead. x2apic emulation is available on KVM since 2009 (Linux 2.6.32-rc1), there's no reason for not enabling x2apic by default when running KVM.

There isn't any kind of "registration" involved in cpu_x86_register() anymore: it is simply looking up a CPU model name and loading the model definition data into the X86CPU object.
