296c024292 USB: usbnet reports minidriver name through ethtool
Update "usbnet" so that ethtool reports the name of the minidriver in use
(e.g. asix, cdc_ether, dm9601, rndis_host) instead of "usbnet".  This is a
better match to how other network drivers work, resolving a minor open issue.

ddda086240 USB: rndis_host, various cleanups
Cleanups to the rndis_host code, and a tweak that helps talking to
PXA hardware.  Mostly from Ole André Vadla Ravnås <oleavr@gmail.com>

  - Prevent SET_INTERFACE requests, they give PXA hardware bad indigestion
  - For paranoia, null a pointer after freeing its data
  - Wrap up ActiveSync oddities for RNDIS_QUERY in one routine
  - Use that wrapper when getting the Ethernet address
  - Whitespace fixes

Plus add a comment noting the open issues about some RNDIS clients still
needing TBD kinds of browbeating to accept non-jumbogram packets.

ecb658d387 usbmon: bus zero
Add the "bus zero" feature to the usbmon. If a user process specifies bus
with number zero, it receives events from all buses. This is useful when
we wish to see initial enumeration when a bus is created, typically after
a modprobe. Until now, an application had to loop until a new bus could
be open, then start capturing on it. This procedure was cumbersome and
could lose initial events. Also, often it's too bothersome to find exactly
to which bus a specific device is attached.

Paolo Albeni provided the original concept implementation. I added the
handling of "bus->monitored" flag and generally fixed it up.

35d07fd58f USB: Allow transfer_buffer with transfer_dma
Some host controller drivers may need a PIO fallback when a DMA channel
is temporarily unavailable.  This patch provides an address that such
drivers can use for PIO in those cases, and nulls that field out when
no such address is available (highmem) which should help usbmon.

1941044aa9 USB: add "last_busy" field for use in autosuspend
This patch (as877) adds a "last_busy" field to struct usb_device, for
use by the autosuspend framework.  Now if an autosuspend call comes at
a time when the device isn't busy but hasn't yet been idle for long
enough, the timer can be set to exactly the desired value.  And we
will be ready to handle things like HID drivers, which can't maintain
a useful usage count and must rely on the time-of-last-use to decide
when to autosuspend.

The patch also makes some related minor improvements:

	Move the calls to the autosuspend condition-checking routine
	into usb_suspend_both(), which is the only place where it
	really matters.

	If the autosuspend timer is already running, don't stop
	and restart it.

	Replace immediate returns with gotos so that the optional
	debugging ouput won't be bypassed.

	If autoresume is disabled but the device is already awake,
	don't return an error for an autoresume call.

	Don't try to autoresume a device if it isn't suspended.
	(Yes, this undercuts the previous change -- so sue me.)

	Don't duplicate existing code in the autosuspend work routine.

	Fix the kerneldoc in usb_autopm_put_interface(): If an
	autoresume call fails, the usage counter is left unchanged.

9f8b17e643 USB: make usbdevices export their device nodes instead of using a separate class
o The "real" usb-devices export now a device node which can
  populate /dev/bus/usb.

o The usb_device class is optional now and can be disabled in the
  kernel config. Major/minor of the "real" devices and class devices
  are the same.

o The environment of the usb-device event contains DEVNUM and BUSNUM to
  help udev and get rid of the ugly udev rule we need for the class
  devices.

o The usb-devices and usb-interfaces share the same bus, so I used
  the new "struct device_type" to let these devices identify
  themselves. This also removes the current logic of using a magic
  platform-pointer.
  The name of the device_type is also added to the environment
  which makes it easier to distinguish the different kinds of devices
  on the same subsystem.

  It looks like this:
    add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1
    ACTION=add
    DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1
    SUBSYSTEM=usb
    SEQNUM=1533
    MAJOR=189
    MINOR=131
    DEVTYPE=usb_device
    PRODUCT=46d/c03e/2000
    TYPE=0/0/0
    BUSNUM=002
    DEVNUM=004

This udev rule works as a replacement for usb_device class devices:
  SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \
    NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0644"

Updated patch, which needs the device_type patches in Greg's tree.

I also got a bugzilla assigned for this. :)

suspend and resume requests, as opposed to internally-generated
autosuspend or autoresume.  It also changes the existing
remote-wakeup code paths to use the new routines, since remote wakeup
is not the same as autoresume.

As part of the change, it turns out to be necessary to do remote
wakeup of root hubs from a workqueue.  We had been using khubd, but it
does autoresume rather than an external resume.  Using the
ksuspend_usb_wq workqueue for this purpose seemed a logical choice.

e9b8daf31b usbatm: create sysfs link "device" from atm class device to usb interface
There is currently no path from the ATM device in /sys to the USB device's
interface that the driver is using; this patch creates a "device" symlink.  It
is then possible to get to the cxacru ADSL statistics
(http://lkml.org/lkml/2007/2/23/328):

/sys/class/atm/cxacru0/device $ ls *_rate *_margin *_attenuation
downstream_attenuation  downstream_snr_margin  upstream_rate
downstream_rate         upstream_attenuation   upstream_snr_margin

If this link is not appropriate I'd have to create device files in
/sys/class/atm/cxacru0 instead - which seems less appropriate since the ADSL
statistics are for the USB device not ATM (which is running over the ADSL).

718efa64e3 usbcore: move usb_autosuspend_work
This patch (as864) moves the work routine for USB autosuspend from one
source file to another.  This permits the removal of one whole global
symbol (!) and should smooth the way for more changes in the future.

64e35d9236 libusual: change block scope variable to function scope
Someone changed the code to kthread and used his style instead of mine.

The problem with the block variables is that they provoke shadowing,
which is actually exactly what has happened in my other tree which
has the class patch.

643616e678 ub: Bind to first endpoint, not to last
The usb-storage switched to binding to first endpoint recently. Apparently,
there are devices out there with extra endpoints. It is perfectly legal.
