[Qemu-devel] [PATCH 2/9] target-i386: Move TCG initialization to realize time

[Eduardo Habkost <ehabkost@redhat.com>]

QOM instance_init functions are not supposed to have any side-effects,
as new objects may be created at any moment for querying property
information (see qmp_device_list_properties()).

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

Changes v1 -> v2:
 * Now the inited/tcg_initialized variable doesn't exist anymore
 * Move tcg_x86_init() call after basic parameter validation inside
   realizefn
