Upstream changed the default rootfs to tmpfs when none has been passed
to the kernel - this doesn't fit our purposes, so change it back.

Subject: [PATCH 11/12] USB: EHCI: add ignore_oc flag to disable overcurrent
checking
This patch adds an ignore_oc flag which can be set by EHCI controller
not supporting or wanting to disable overcurrent checking. The EHCI
platform data in include/linux/usb/ehci_pdriver.h is also augmented to
take advantage of this new flag.

Subject: bridge: allow receiption on disabled port
When an ethernet device is enslaved to a bridge, and the bridge STP
detects loss of carrier (or operational state down), then normally
packet receiption is blocked.
This breaks control applications like WPA which maybe expecting to
receive packets to negotiate to bring link up. The bridge needs to
block forwarding packets from these disabled ports, but there is no
hard requirement to not allow local packet delivery.
