I would consider these stable candidates too:

1)       ehci: Don't set seen to 0 when removing unseen queue-heads
2)       ehci: Don't process too much frames in 1 timer tick (v2)
3)       ehci: Fix interrupts stopping when Interrupt Threshold Control is 8

1) Fixes us canceling packets we should not cancel when we hit a high timer
latency directly after the doorbell
2) Fixes streaming isoc data failing with "failed to resubmit urb (-27) errors
in dmesg in the guest with Linux guests, this bug has existed for ages, but
migration triggered it almost always, making me look into it
3) Is an obvious bugfix in itself, I'm not sure there are any guests hitting this,
but the fix is so trivial it cannot hurt.

Hans
