Could you please confirm that the boot problem has been fixed
on the qemu side? I guess that it is
https://github.com/img-meta/qemu/commit/0a2402860228198ae2729048f1de05aeedb7d642

Could Andrew enable all the kthread worker API improvements in -mm
tree again?

I think that kthread worker patch has been an innocent victim.
It added some functions that were not used anywhere. I think
that it has triggered the boot problem just by chance.
