Sure, I'll do the rebase today.

What about the preparation patch series, from where this one is
placed on the top:

	https://lore.kernel.org/qemu-devel/cover.1733297707.git.mchehab+huawei@kernel.org/T/#m3b56bbe7bd400369f9e38b56faf4e65e64069955

Could you merge it? It should apply cleanly on

	https://gitlab.com/qemu-project/qemu.git master

and it doesn't contain any migration stuff on it.

Thanks,
Mauro
