Pull networking fixes from David Miller:
1) Name string overrun fix in gianfar driver from Joe Perches.
2) VHOST bug fixes from Michael S. Tsirkin and Nadav Har'El
3) Fix dependencies on xt_LOG netfilter module, from Pablo Neira Ayuso.
4) Fix RCU locking in xt_CT, also from Pablo Neira Ayuso.
5) Add a parameter to skb_add_rx_frag() so we can fix the truesize
adjustments in the drivers that use it. The individual drivers
aren't fixed by this commit, but will be dealt with using follow-on
commits. From Eric Dumazet.
6) Add some device IDs to qmi_wwan driver, from Andrew Bird.
7) Fix a potential rcu_read_lock() imbalancein rt6_fill_node(). From
Eric Dumazet.

skb_add_rx_frag() API is misleading.
Network skbs built with this helper can use uncharged kernel memory and
eventually stress/crash machine in OOM.
Add a 'truesize' parameter and then fix drivers in followup patches.

This patch changes the ARCH name to "ARCH_S3C24XX" for Samsung
S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443,
and S3C2450 SoCs so that we can merge the mach-xxx directories
and plat-s3c24xx dir. to just one mach-s3c24xx for them.
I think this should be sent to upstream via samsung tree because
this touches many samsung stuff.

Greg's e-mail address was old. So, I resend it.
Though I've tested this patch,
http://marc.info/?l=linux-usb&m=132825305710285&w=2,
I've received the following reports.
http://kisskb.ellerman.id.au/kisskb/buildresult/5771890/
http://kisskb.ellerman.id.au/kisskb/buildresult/5771905/
So, I added header file for these symbols.
Using this patch, this compile error must be disappeared.

A read from GadgetFS endpoint 0 during the data stage of a control
request would always return 0 on success (as returned by
wait_event_interruptible) despite having written data into the user
buffer.
This patch makes it correctly set the return value to the number of
bytes read.

As the coverity checker puts it:
"Passing argument "sizeof (midi_function) /*8*/" to function "kcalloc"
and then casting the return value to "struct usb_descriptor_header **"
is suspicious. ... In this particular case sizeof(struct
usb_descriptor_header **) happens to be equal to sizeof(struct
usb_descriptor_header *), but this is not a portable assumption."
I believe we really do intend to use 'sizeof(*midi_function)' here, so
this patch makes that change.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
USB: Gadget: changes for 3.4
This merge is rather big. Here's what it contains:
For am5536udc we have just simple coding style fixes. Nothing that has any
potential to cause any issues going forward.
With mv_udc, there's only one single change removing an unneeded NULL check.
at91_udc also only saw a single change this merge window, and that's only
removing a duplicated header.
The Renesas controller has a few more involved changes. Support for SUDMAC was
added, there's now a special handling of IRQ resources for when the IRQ line is
shared between Renesas controller and SUDMAC, we also had a bug fix where
Renesas controller would sleep in atomic context while doing DMA transfers from
a tasklet. There were also a set of minor cleanups.
The FSL UDC also had a scheduling in atomic context bug fix, but that's all.
Thanks to Sebastian, the dummy_hcd now works better than ever with support for
scatterlists and streams. Sebastian also added SuperSpeed descriptors to the
serial gadgets.
The highlight on this merge is the addition of a generic API for mapping and
unmapping usb_requests. This will avoid code duplication on all UDC controllers
and also kills all the defines for DMA_ADDR_INVALID which UDC controllers
sprinkled around. A few of the UDC controllers were already converted to use
this new API.

such utilities are currently duplicated on all UDC
drivers basically with the same structure. Let's group
all implementations into one generic implementation
and get rid of that duplication.

The reason of above dump message is calling dma_poll_alloc with can-schedule
mem_flags at atomic context.
To fix this problem, below changes are made:
- fsl_req_to_dtd doesn't need to be protected by spin_lock_irqsave,
as struct usb_request can be access at process context. Move lock
to beginning of hardware visit (fsl_queue_td).
- Change the memory flag which using to allocate dTD descriptor buffer,
the memory flag can be from gadget layer.
It is tested at i.mx51 bbg board with g_mass_storage, g_ether, g_serial.

This is a flexible USB Audio Class 2.0 compliant gadget driver that
implements a simple topology with a virtual sound card exposed at
the function side.
The driver doesn't expect any real audio codec to be present on the
function - the audio streams are simply sinked to and sourced from a
virtual ALSA sound card created. The user-space application may choose
to do whatever it wants with the data received from the USB Host and
choose to provide whatever it wants as audio data to the USB Host.
Capture(USB-Out) and Playback(USB-In) can be run at independent
configurations specified via module parameters while loading the driver.
Make this new version as the default selection by a new Kconfig choice.

This patch adds SS descriptors to the ACM & generic serial gadget. The
ACM part was tested with minicom + dummy + send / receive files over
ttyACM <=> ttyGS0.
The generic serial part (f_serial) was not tested (haven't found a
driver on the host side).
The nokia & multi gadget use HS at most.

Since commit 72c973dd aka ("usb: gadget: add usb_endpoint_descriptor to
struct usb_ep) the descriptor is part of the ep. Most gadgets like
g_zero or masstorage call config_ep_by_speed() to grab an available
endpoint which may be used for FS/HS/SS bulk/iso/intr and in a second
they assign the proper descriptor by calling config_ep_by_speed(). This
is good so far. A few of them like ncm call config_ep_by_speed() only if
ep->desc not assigned earlier. That means ep->desc is never assigned if
the endpoint was used by another gadget before it was removed.
Some of those gadgets also assign ep->driver_data to NULL on reset or
ep_disable part _but_ keep a reference to this endpoint. At ep_enable
time they assign driver_data to their private data. This probably needs
a clean up of its own.

Problem:
pch_udc continues operation even if VBUS becomes Low.
pch_udc performs D+ pulling up before VBUS becomes High.
USB device should be controlled according to VBUS state.
Root cause:
The current pch_udc is not always monitoring VBUS.
Solution:
The change of VBUS is detected using an interrupt of GPIO.
If VBUS became Low, pch_udc handles 'disconnect'.
After VBUS became High, a pull improves D+, and pch_udc
handles 'connect'.

Problem:
In USB Suspend, pch_udc handles 'disconnect'.
Root cause:
The current pch_udc is not monitoring VBUS.
When USB cable is disconnected, USB Device Controller generates
an interrupt of USB Suspend.
pch_udc cannot distinguish it is USB Suspend or disconnect.
Therefore, pch_udc handles 'disconnect' after an interrupt of
USB Suspend happend.
Solution:
VBUS is detected through GPIO.
After an interrupt produced USB Suspend, if VBUS is Low,
pch_udc handles 'disconnect'.
If VBUS is High, pch_udc handles 'suspend'.

If the stream check fails then we leave ep->desc assigend but we return
with an error code. The caller assumes the endpoint is not enabled
(which is the case) but it can not enable it again due to this
assigment.
