+Subject: usb: gadget: fsl_udc_core: dTD's next dtd pointer need to be updated once written
+
+From: Peter Chen <peter.chen@freescale.com>
+
+commit 4d0947dec4db1224354e2f6f00ae22ce38e62a43 upstream.
+
+dTD's next dtd pointer need to be updated once CPU writes it, or this
+request may not be handled by controller, then host will get NAK from
+device forever.
+
+This problem occurs when there is a request is handling, we need to add
+a new request to dTD list, if this new request is added before the current
+one is finished, the new request is intended to added as next dtd pointer
+at current dTD, but without wmb(), the dTD's next dtd pointer may not be
+updated when the controller reads it. In that case, the controller will
+still get Terminate Bit is 1 at dTD's next dtd pointer, that means there is
+no next request, then this new request is missed by controller.

+
+There exist races in devio.c, below is one case,
+and there are similar races in destroy_async()
+and proc_unlinkurb(). Remove these races.

+ Lead to free_async() be triggered,
+ then urb and 'as' will be freed.
+
+ usb_unlink_urb(as->urb);

+Subject: xhci: Add Lynx Point to list of Intel switchable hosts.
+
+From: Sarah Sharp <sarah.a.sharp@linux.intel.com>
+
+commit 1c12443ab8eba71a658fae4572147e56d1f84f66 upstream.
+
+The upcoming Intel Lynx Point chipset includes an xHCI host controller
+that can have ports switched from the EHCI host controller, just like
+the Intel Panther Point xHCI host. This time, ports from both EHCI
+hosts can be switched to the xHCI host controller. The PCI config
+registers to do the port switching are in the exact same place in the
+xHCI PCI configuration registers, with the same semantics.
+
+Hooray for shipping patches for next-gen hardware before the current gen
+hardware is even available for purchase!
+
+This patch should be backported to stable kernels as old as 3.0,
+that contain commit 69e848c2090aebba5698a1620604c7dccb448684
+"Intel xhci: Support EHCI/xHCI port switching."
