After some hand-bisecting and real-bisecting, I found two commits that
cause problems for 3.13: With these reverted, I get usb networking
back in 3.13 on nokia n900.
(Pali, if you revert these, you should get working usb networking in
your 3.13 branch, too.)
Any ideas?

usb: musb: omap2430: use the new generic PHY framework
Use the generic PHY framework API to get the PHY. The
usb_phy_set_resume
and usb_phy_set_suspend is replaced with power_on and
power_off to align with the new PHY framework.
musb->xceiv can't be removed as of now because musb core uses
xceiv.state and
xceiv.otg. Once there is a separate state machine to handle otg,
these can be
moved out of xceiv and then we can start using the generic PHY
framework.
