Mainly style: QOM uses the parent's struct as field to block the memory
but otherwise attempts to hide this field from users:

/*< private >*/
FooState parent_obj;
/*< public >*/

Bar baz;
...

In the past I found places where this was mangled up and the parent
field was not the first field as it needs to be, not caught by the qdev
macros.

I have hopes that when we preprocess for QIDL we can also improve the
vtable situation, possibly inserting the parents' fields individually.
Either way my don't-touch-the-parent cleanups will turn useful. ;)

Maybe? I wouldn't know where or how since it's not within one line...
And last time I attempted to change checkpatch.pl, my patches were
turned down. :(

Just found out that the apm patch trivially conflicts (hw/lpc_ich9.c) -
you added a notifier whereas Julien changed apm_init() signature.
I can update my branch once Anthony has pulled yours.
