f3bb8e63a8 usb: gadget: at91udc: Don't check for ep->ep.desc
Earlier we used to check for ep->ep.desc to figure out if this ep has
already been enabled and if so, abort.
Ido Shayevitz removed the usb_endpoint_descriptor from private udc
structure 5a6506f00 ("usb: gadget: Update at91_udc to use
usb_endpoint_descriptor	inside the struct usb_ep") but did not fix up
the ep_enable condition because _now_ the member is always true and we
can't check if this ep is enabled twice.

8b7dda554c usb: gadget: at91udc: don't overwrite driver data
The driver was converted to the new start/stop interface in f3d8bf34c2
("usb: gadget: at91_udc: convert to new style start/stop interface").
I overlooked that the driver is overwritting the private data which is
used by the composite framework. The udc driver doesn't read it, it is
only written here.

1b68a4ca2d usb: gadget: dummy_hcd: fixup error probe path
If USB2 host controller probes fine but USB3 does not then we don't
remove the USB controller properly and lock up the system while the HUB
code will try to enumerate the USB2 controller and access memory which
is no longer available in case the dummy_hcd was compiled as a module.

This is a problem since 448b6eb1 ("USB: Make sure to fetch the BOS desc
for roothubs.) if used in USB3 mode because dummy does not provide this
descriptor and explodes later.

85b8614d72 usb: gadget: get rid of USB_GADGET_{DUAL,SUPER}SPEED
This commit removes USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED
Kconfig options.  Since now kernel allows many UDC drivers to be
compiled, those options may turn to no longer be valid.  For
instance, if someone decides to build UDC that supports super
speed and UDC that supports high speed only, the latter will be
"assumed" to support super speed since USB_GADGET_SUPERSPEED will
be selected by the former.

The test of whether CONFIG_USB_GADGET_*SPEED was defined was just
an optimisation which removed otherwise dead code (ie. if UDC is
not dual speed, there is no need to handle cases that can happen
if speed is high).  This commit removes those checks.

974e9323de usb: gadget: udc-core: Race between disconnect/unbind and setup
usb_gadget_remove_driver() runs through a four-step sequence to shut down
the gadget driver.  For the case of a composite gadget + at91 UDC, this
would look like:

    udc->driver->disconnect(udc->gadget);          // composite_disconnect()
    usb_gadget_disconnect(udc->gadget);            // at91_pullup(gadget, 0)
    udc->driver->unbind(udc->gadget);              // composite_unbind()
    usb_gadget_udc_stop(udc->gadget, udc->driver); // at91_stop()

The UDC driver can receive SETUP packets from the host up until the
point when usb_gadget_disconnect() returns.  On rare occasions, the
gadget driver may see this sequence:

    udc->driver->disconnect(udc->gadget);          // composite_disconnect()
    udc->driver->setup(udc->gadget, &ctrl);        // composite_setup()
    udc->driver->unbind(udc->gadget);              // composite_unbind()

Some gadget drivers, such as composite, assume this will never happen
and crash as a result.

The fix is to quiesce the UDC hardware (via usb_gadget_disconnect)
before running the gadget driver through the disconnect/unbind sequence.

2868fea2d6 usb: gadget: s3c-hsotg: fix core reset timeout failure
The timeout values were 1000 and timeout issue occured many times on my
s3c6410 Soc based board (mostly when booting whith USB cable not
connected). This patch increase the values to 10000 to guarantee the
success of reset.

Having set timeout to 10000, I printed the remained timeout values
which could cause timeout issue before this change (tested several
times).
the first timeout value remained:
	timeout = 8079
	timeout = 8079
	timeout = 8078
	timeout = 8081
the second timeout value remained:
	timeout = 7940
	timeout = 7945
	timeout = 7940
	timeout = 7938
Seeing from above values, I think the value 10000 is big enough.

11c37c8b64 usb: gadget: mv_udc: fix boot up hang
Fix boot up hang when enable udc without otg enabled.
The root cause is that the clock will be shut down when probe routine is
finished because of clock gating. When a gadget driver is registered at
this time, it will call mv_udc_start which in turn will call
mv_udc_vbus_session. If there is no cable attached at the boot up time,
the vbus is low, so it will call stop_activity path without clock
enabled which will cause system hang then.
Actually, we need't go this path when clock is disabled, what we need to
do is just jump out.

43829731dd workqueue: deprecate flush[_delayed]_work_sync()
flush[_delayed]_work_sync() are now spurious.  Mark them deprecated
and convert all users to flush[_delayed]_work().

If you're cc'd and wondering what's going on: Now all workqueues are
non-reentrant and the regular flushes guarantee that the work item is
not pending or running on any CPU on return, so there's no reason to
use the sync flushes at all and they're going away.

This patch doesn't make any functional difference.

734cc17838 TTY: use tty_port_register_device
Currently we have no way to assign tty->port while performing tty
installation. There are two ways to provide the link tty_struct =>
tty_port. Either by calling tty_port_install from tty->ops->install or
tty_port_register_device called instead of tty_register_device when
the device is being set up after connected.

In this patch we modify most of the drivers to do the latter. When the
drivers use tty_register_device and we have tty_port already, we
switch to tty_port_register_device. So we have the tty_struct =>
tty_port link for free for those.

b1b552a69b usb: gadget: u_ether: fix kworker 100% CPU issue with still used interfaces in eth_stop
This patch fixes an issue introduced by patch:

    72c973d usb: gadget: add usb_endpoint_descriptor to struct usb_ep

Without this patch we see a kworker taking 100% CPU, after this sequence:

- Connect gadget to a windows host
- load g_ether
- ifconfig up <ip>; ifconfig down; ifconfig up
- ping <windows host>

The "ifconfig down" results in calling eth_stop(), which will call
usb_ep_disable() and, if the carrier is still ok, usb_ep_enable():

         usb_ep_disable(link->in_ep);
         usb_ep_disable(link->out_ep);
         if (netif_carrier_ok(net)) {
                 usb_ep_enable(link->in_ep);
                 usb_ep_enable(link->out_ep);
         }

The ep should stay enabled, but will not, as ep_disable set the desc
pointer to NULL, therefore the subsequent ep_enable will fail. This leads
to permanent rescheduling of the eth_work() worker as usb_ep_queue()
(called by the worker) will fail due to the unconfigured endpoint.

We fix this issue by saving the ep descriptors and re-assign them before
usb_ep_enable().

 "This patch series contains a major revamp of how we collect entropy
  from interrupts for /dev/random and /dev/urandom.

  The goal is to addresses weaknesses discussed in the paper "Mining
  your Ps and Qs: Detection of Widespread Weak Keys in Network Devices",
  by Nadia Heninger, Zakir Durumeric, Eric Wustrow, J.  Alex Halderman,
  which will be published in the Proceedings of the 21st Usenix Security
  Symposium, August 2012.  (See https://factorable.net for more
  information and an extended version of the paper.)"

0614002bb5 netvm: propagate page->pfmemalloc from skb_alloc_page to skb
The skb->pfmemalloc flag gets set to true iff during the slab allocation
of data in __alloc_skb that the the PFMEMALLOC reserves were used.  If
page splitting is used, it is possible that pages will be allocated from
the PFMEMALLOC reserve without propagating this information to the skb.
This patch propagates page->pfmemalloc from pages allocated for fragments
to the skb.

It works by reintroducing and expanding the skb_alloc_page() API to take
an skb.  If the page was allocated from pfmemalloc reserves, it is
automatically copied.  If the driver allocates the page before the skb, it
should call skb_propagate_pfmemalloc() after the skb is allocated to
ensure the flag is copied properly.

Failure to do so is not critical.  The resulting driver may perform slower
if it is used for swap-over-NBD or swap-over-NFS but it should not result
in failure.

569a50da7f gadget/r8a66597: remove conditional compilation of clk code
With addition of dummy clk_*() calls for non CONFIG_HAVE_CLK cases in
clk.h, there is no need to have clk code enclosed in #ifdef
CONFIG_HAVE_CLK, #endif macros.

Pull USB patches from Greg Kroah-Hartman:
 "Here's the big USB patch set for the 3.6-rc1 merge window.

  Lots of little changes in here, primarily for gadget controllers and
  drivers.  There's some scsi changes that I think also went in through
  the scsi tree, but they merge just fine.  All of these patches have
  been in the linux-next tree for a while now.
