I have a patch removing _irqsave/_irqrestore from our spin_lock calls in XHCI's IRQ handler and it's still working fine. I have 7x 8GiB HS devices on a hub, set them up as raid0 and I'm reading/writing to this raid0 device. So far no problems. I'll test this further with other devices to see if no issues surface, but expect another patch to this series (assuming people are okay with the change). -- balbi
