logic.  It was leaving ITDs and SITDs on the schedule too long, for
a few different reasons, which caused trouble.

  (a) Look at all microframes for high speed transfers, not just
the ones we expect to have finished.  This way transfers
ending mid-frame will complete without needing another IRQ.
This also minimizes bogus scheduling underruns (e.g. EL2NSYNC).

  (b) When we encounter an ISO transfer (either speed, but this
hits mostly at full speed) that's not yet been completed,
immediately stop scanning; we've caught up to the hardware,
no matter what other indications might say.

  (c) Always clean up ITDs (for high speed transfers) when the HC
is no longer running.

USB: PS3: Fix EHCI ISO transfer bug

This adds a workaround for an issue reported with ISO transfers
on some EHCI controllers, most recently with VIA KT800 and PS3
EHCI silicon.

The issue is that the silicon doesn't necessarily seem to be done
using ISO DMA descriptors (itd, sitd) when it marks them inactive.
(One theory is that the ill-defined mechanism where hardware caches
periodic transfer descriptors isn't invalidating their state...)
With such silicon, quick re-use of those descriptors makes trouble.
Waiting until the next frame seems to be a sufficient workaround.

This patch ensures that the relevant descriptors aren't available
for immediate re-use.  It does so by not recycling them until after
issuing the completion callback which would reuse them by enqueueing
an URB and thus (re)allocating ISO DMA descriptors.

USB: usb_serial_console: allocate fake tty and termios before calling driver open() method

The usb serial method set_termios() is called for the first time from
open() method in order to set up the termios structure with the default
device's settings, ignoring the current settings. Once it's initialized,
the next set_termios() calls will update the device with the
tty->termios settings.
Currently USB serial console code calls the driver open() method without
a tty and after that will allocate a fake tty and termios so the command
line arguments can be applied to the device
(console=ttyUSB0,115200,...). This makes the driver overwrite the
termios with the default settings and not applying the command line
options.

USB: usb_serial: clean tty reference in the last close

When a usb serial adapter is used as console, the usb serial console
driver bumps the open_count on the port struct used but doesn't attach
a real tty to it (only a fake one temporaly). If this port is opened later
using the regular character device interface, the open method won't
initialize the port, which is the expected, and will receive a brand new
tty struct created by tty layer, which will be stored in port->tty.

When the last close is issued, open_count won't be 0 because of the
console usage and the port->tty will still contain the old tty value. This
is the last ttyUSB<n> close so the allocated tty will be freed by the
tty layer. The usb_serial and usb_serial_port are still in use by the
console, so port_free() won't be called (serial_close() ->
usb_serial_put() -> destroy_serial() -> port_free()), so the scheduled
work (port->work, usb_serial_port_work()) will still run. And
usb_serial_port_work() does:
(...)
        tty = port->tty;
        if (!tty)
                return;

        tty_wakeup(tty);

USB: Variant of the Dell Wireless 5520 driver

I've got a Dell wireless 5520 card with a different USB ID - specifically, 8136
instead of 8137. Attached a small patch to add support, and the output of an
'ati3'.

If we could get this in, that'd be sweet.  ;)  Thanks!

this function will run in the context of the scsi error handler thread.
It must use GFP_NOIO instead of GFP_KERNEL to avoid a possible
deadlock.
