[AF_IUCV/IUCV]: smp_call_function deadlock
Calling smp_call_function can lead to a deadlock if it is called
from tasklet context.
Fixing this deadlock requires to move the smp_call_function from the
tasklet context to a work queue. To do that queue the path pending
interrupts to a separate list and move the path cleanup out of
iucv_path_sever to iucv_path_connect and iucv_path_pending.
This creates a new requirement for iucv_path_connect: it may not be
called from tasklet context anymore.
Also fixed compile problem for CONFIG_HOTPLUG_CPU=n and
another one when walking the cpu_online mask. When doing this,
we must disable cpu hotplug.

sis900: Allocate rx replacement buffer before rx operation
Just found a hole in my last patch. It was reported to me that shortly after we
integrated this patch. The report was of an oops that took place inside of
netif_rx when using the sis900 driver. Looking at my origional patch I noted
that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame. The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring. So if you receive frames fast enough the skb being processed by
the network stack can get corrupted. The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP. I'll post test results when I hear
them, but I think this is a pretty straightforward fix. It just uses a separate
pointer to do the rx operation, so that we don't improperly reassign the pointer
that we use to refill the rx ring.

(These timeouts seemed to work fine for all users of the driver, at

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.

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.

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"

USB: MAINTAINERS: cxacru
I've acquired a second device for testing and plan to make some changes in
the near future to export all the device stats to sysfs (based on my
proposed patch to add them to the proc file ~2007-01-30).

USB: cxacru: export detailed device info through sysfs
When the device is polled for status there is a lot of useful status
information available that is ignored. This patch stores the device info
array when the status is polled and adds sysfs files to the usb device to
allow userspace to query it. Since the device updates its status
internally once a second the poll time is changed to this, and
round_jiffies_relative is used to avoid waking the cpu unnecessarily.

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).

usbcore: move usb_autosuspend_work
This patch (as864) moves the work routine for USB autosuspend from one

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,
