Thomas originally suggested taking the genirq change himself and then 
providing a tag for others to merge:

https://lore.kernel.org/linux-scsi/87h7qf1yp0.fsf@nanos.tec.linutronix.de/

Not sure if that still stands. The small ACPI change could go in a cycle 
after rest merged, but may be best not to split up.

The worst that will happen without Marc's series is that is remove + 
re-probe the SCSI driver is broken, so I'm happy as long as that ends up 
in same kernel version somehow:
