10) Prevent neighbour overflows in ipv6 for locally destined routes,
from Marcelo Ricardo. This is the best short-term fix for this, a
longer term fix has been implemented in net-next.
11) L2TP uses ipv4 datagram routines in it's ipv6 code, whoops. This
mistake is largely because the ipv6 functions don't even have some
kind of prefix in their names to suggest they are ipv6 specific.

resource releasing in error path of xen_netbk_get_requests(). From
Ian Campbell.
18) SCTP authentication keys should be cleared out and released with
kzfree(), from Daniel Borkmann.
19) L2TP is a bit too clever trying to maintain skb->truesize, and ends
up corrupting socket memory accounting to the point where packet
sending is halted indefinitely. Just remove the adjustments
entirely, they aren't really needed. From Eric Dumazet.
20) ATM Iphase driver uses a data type with the same name as the S390
headers, rename to fix the build. From Heiko Carstens.

A device sending 0 length frames as fast as it can has been
observed killing the host system due to the resulting memory
pressure.
Temporarily disable RX skb allocation and URB submission when
the current error ratio is high, preventing us from trying to
allocate an infinite number of skbs. Reenable as soon as we
are finished processing the done queue, allowing the device
to continue working after short error bursts.

This patch (as1649) adds a mechanism for host controller drivers to
inform usbcore when they have begun or ended resume signalling on a
particular root-hub port. The core will then make sure that the root
hub does not get runtime-suspended while the port resume is going on.
Since commit 596d789a211d134dc5f94d1e5957248c204ef850 (USB: set hub's
default autosuspend delay as 0), the system tries to suspend hubs
whenever they aren't in use. While a root-hub port is being resumed,
the root hub does not appear to be in use. Attempted runtime suspends
fail because of the ongoing port resume, but the PM core just keeps on
trying over and over again. We want to prevent this wasteful effort.

The old parameter "port" is useless for phy notify, as one usb
phy is only for one usb port. New parameter "speed" stands for
the device's speed which is on the port, this "speed" parameter
is needed at some platforms which will do some phy operations
according to device's speed.

USB gadget patches from Felipe:
"usb: gadget: patches for v3.8
renesas_usbhs implements ->pullup() method, switches over
to devm_request_irq(), adds support for DMA Engine and
got a few miscelaneous cleanups.
The NCM gadget got an endianness fix and the Ethernet
gadget a frame size fix.
We're finally removing the g_file_storage gadget and
sticking to g_mass_storage and the new tcm_usb_gadget
gadgets since that was a huge duplicaton of effort anyway.
While removing g_file_storage, we also had to fix a bunch
of defconfigs which were still pointing to the old gadget.
There's a big series getting us closer to being able to
introduce our configfs interface. The series converts
functions into loadable modules which will, eventually,
be registered to the configfs interface.
Other than that there's the usual typo fixes and miscelaneous
cleanups all over the place."

This patch (as1623) removes the ehci_port_power() routine and all the
places that call it. There's no reason for ehci-hcd to change the
port power settings; the hub driver takes care of all that stuff.
There is one exception: When the controller is resumed from
hibernation or following a loss of power, the ports that are supposed
to be handed over to a companion controller must be powered on first.
Otherwise the handover won't work. This process is not visible to the
hub driver, so it has to be handled in ehci-hcd.

HS and SS descriptors are staticaly created. They are updated during the
bind process with the endpoint address, string id or interface numbers.
After that, the descriptor chain is linked to struct usb_function which
is used by composite in order to serve the GET_DESCRIPTOR requests,
number of available configs and so on.
There is no need to assign the HS descriptor only if the UDC supports
HS speed because composite won't report those to the host if HS support
has not been reached. The same reasoning is valid for SS.
This patch makes sure each function updates HS/SS descriptors
unconditionally and uses the newly introduced helper function to create a
copy the descriptors for the speed which is supported by the UDC.
While at that, also rename f->descriptors to f->fs_descriptors in order
to make it more explicit what that means.

The CDC Mobile Broadband Interface Model (MBIM) specification
extends CDC NCM by
- removing the redundant ethernet header from the point-to-point
USB channel
- adding support for multiple IP (v4 and/or v6) sessions multiplexed
on the same USB channel
- adding a MBIM control channel encapsulated in CDC
- adding Device Service Streams (DSS), which are non IP generic data
streams multiplexed on the same USB channel as the IP sessions
MBIM devices are managed using the dedicated control channel, and no
data will flow on the data channel until a control session has been
established. This driver has no knowledge of MBIM control messages.
It just exports the control channel to a /dev/cdc-wdmX character
device for userspace management applications. Such an application is
therefore required to use this driver.
This patch implements basic MBIM support, reusing the NCM and WDM driver
APIs, currently limited to IP sessions with SessionID 0. DSS and
multiplexed IP sessions are not yet supported.

Enhance the ehci-platform driver to also accept no_io_watchdog as a platform

ehci->need_io_watchdog to 0. Since most EHCI controllers do need the I/O
watchdog to be on, only let those which need it to turn the watchdog off.
Make sure that we change need_io_watchdog after the call to ehci_setup()
because ehci_setup() will unconditionnaly set need_io_watchdog to 1.

Just like for the in-tree early console debug port driver, the
hypervisor - when using a debug port based console - also needs to be
told about controller resets, so it can suppress using and then
re-initialize the debug port accordingly.
Other than the in-tree driver, the hypervisor driver actually cares
about doing this only for the device where the debug is port actually
in use, i.e. it needs to be told the coordinates of the device being
reset (quite obviously, leveraging the addition done for that would
likely benefit the in-tree driver too).

usb: xceiv: patches for v3.7 merge window
nop xceiv got its own header to avoid polluting otg.h. It has also
learned to work as USB2 and USB3 phys so we can use it on USB3
controllers.
Together with those two changes to nop xceiv, we're adding basic
PHY support to dwc3 driver, this is to allow platforms which actually
have a SW-controllable PHY talk to them through dwc3 driver.
We're adding a new phy driver for the OMAP architecture. This driver
is for the PHY found in OMAP4 SoCs, and a new phy driver for the
marvell architecture. An extra phy driver - for Tegra SoCs - is now
moving from arch/arm/mach-tegra* to drivers/usb/phy.
Also here, there's the creation of <linux/usb/phy.h> which should be
used from now on for PHY drivers, even those which don't support
OTG.

making renesas_hsbhs' irq handler Shared, unused code being dropped,
prevention of sleep-inside-spinlock bugs and a race condition fix

The bcdDevice field is defined as
|Device release number in binary-coded decimal
in the USB 2.0 specification. We use this field to distinguish the UDCs
from each other. In theory this could be used on the host side to apply
certain quirks if the "special" UDC in combination with this gadget is
used. This hasn't been done as far as I am aware. In practice it would
be better to fix the UDC driver before shipping since a later release
might not need this quirk anymore.
There are some driver in tree (on the host side) which use the bcdDevice
field to figure out special workarounds for a given firmware revision.
This seems to make sense. Therefore this patch converts all gadgets
(except a few) to use the kernel version instead a random 2 or 3 plus
the UDC number. The few that don't report kernel's version are:
- webcam
This one reports always a version 0x10 so allow it to do so in future.
- nokia
This one reports always 0x211. The comment says that this gadget works
only if the UDC supports altsettings so I added a check for this.
- serial
This one reports 0x2400 + UDC number. Since the gadget version is 2.4
this could make sense. Therefore bcdDevice is 0x2400 here.
I also remove various gadget_is_<name> macros which are unused. The
remaining few macros should be moved to feature / bug bitfield.

This patch removes all "custom manufacturer" strings which are the same
as these which are created by composite. Then it moves the creation of
the default manufacturer string to usb_composite_overwrite_options() in
case no command line argument has been used and the entry is still an
empty string.

This patch pushes the iSerialNumber module argument from composite into
each gadget. Once the user uses the module paramter, the string is
overwritten with the final value.

The index in usb_string array is defined by the gadget. The gadget can
choose which index entry it assigns for the serial number and which the
product name. The gadget has just to ensure that the descriptor contains
the proper string id which is assigned by composite.
If the composite layer knows the index of the "default" information
which will be overwritten by module parameters, it can be used later to
overwrite it.

This patch moves the module options idVendor, idProduct and bcdDevice
from composite.c into each gadgets. This ensures compatibility with
current gadgets and removes the global variable which brings me step
closer towards composite.c in libcomposite

This patch moves USB_BUFSIZ into global header file as
USB_COMP_EP0_BUFSIZ. There is currently only one user (f_sourcesink)
besides composite which need it. Ideally f_sourcesink would have its
own ep0 buffer. Lets keep it that way it was for now.

epautoconf has two global variables which count the endpoint number of
last assigned endpoint.
This patch removes the global variable and keeps it as per (UDC) gadget.
While here, the ifdef is removed and now the in and outpoint are
enumerated unconditionally. The dwc3 for instance supports 32 endpoints
in total.

This patch removes the global variable composite in composite.c.
The private data which was saved there is now passed via an additional
argument to the bind() function in struct usb_gadget_driver.
Only the "old-style" UDC drivers have to be touched here, new style are
doing it right because this change is made in udc-core.
