[Qemu-devel] [PATCH 5/6] target-i386: Move TCG initialization to realize time

[Eduardo Habkost]

To ask the CPU classes for CPU model information and allow QOM
properties to be queried by qmp_device_list_properties(), we need to be
able to safely instantiate a X86CPU object without any side-effects.

Move TCG initialization to realize time so it won't be called when just
doing object_new() on a X86CPU subclass.
