Driver for the "USB20D" / "USBD" block on BCM6328, BCM6368, BCM6816,
BCM6362, BCM3383, and others.

The hardware block was designed to support networking applications
(direct connection of a home router to a PC), and the endpoint
configuration is fixed.

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.

The lpc32xx_udc driver supported only one controller by defining a global

by dynamic allocation of the struct at probe(). A static struct is kept as a

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.

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.

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.

According to ChipIdea's reference manual in section 8.5.2
"Non-streaming operational mode in device mode", we'd better enable stream

is set.

build_dtd() can be called when hold a spinlock, but GFP_KERNEL may cause
dma_pool_alloc() sleep, So we need use GFP_ATOMIC instead of GFP_KERNEL.
But using GFP_ATOMIC may cause failure when allocating memory, add error
handler to handle it.

Following a report of a crash during an automount expire I found that
the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong.
Not only is the locking wrong but the function is more complex than it
needs to be.

The function is meant to calculate (and dget) the next entry in the list
of directories contained in the root of an autofs mount point (an autofs
indirect mount to be precise). The main problem was that the d_lock of
the owner of the list was not being taken when walking the list, which
lead to list corruption under load. The only other lock that needs to
be taken is against the next dentry candidate so it can be checked for
usability.

  so I didn't trigger this until it was run on a machine with more than
  2GB of MMIO space."

When dumping "Code: " sections from an oops, the trapping instruction
%rip points to can be a string copy

and the line contain a bunch of ":".  Current "cut" selects only the and
the second field output looks funnily overlaid this:

Fix this by selecting the remaining fields too.
