This supports another special case:  devices can revert to the "default"
(address zero) state temporarily in usb_reset_device().

This is the quick fix; 2.6 could get rid of these special cases in ep0
hcd logic by disabling ep0, but 2.4 can't.

Recently we've seen some oopses reported in code that cleaned
up HCs after they died ... like pci-pm not letting ohci-hcd
suspend until after the hardware was partly disabled, or users
removing a Cardbus adapter with ehci-hcd.  One root cause was
that the cleanup called hcd->stop() too many times.

This patch just does the cleanup that's reasonable to do
before the (dead) root hub is cleaned up:  it disconnects
the other devices.  And based on a suggestion from Pavel,
a diagnostic always appears -- avoiding mystery.

This patch has some updates to the hcd pci power management glue:

  - removes now-obsolete comments (driver model now exists)

  - better state transitions:
      * suspending "dead" controllers needn't oops
      * multi-resume case (pm bug) simplified
      * multi-suspend case likewise (not always a bug)
      * should handle transitions other than D0->D3{hot,cold}

  - prepares for usb remote wake up support, which will be
    wanting the driver model suspend/resume code to be ready.

This patch adds some read-only files to ov511's sysfs directory. The
read/write attributes will be added in a future patch. For now, the
read/write-related code is #if'd out to prevent warnings.

This patch converts ov511 to dynamically allocate struct video_device,
using the new interfaces in videodev.[ch]. This is required to safely
support sysfs without races.

This is the first in a series of three patches to convert the ov511
driver's /proc/video interface to sysfs. All V4L drivers must undergo
this conversion now that /proc/video has been removed from the core.

This patch removes ov511's /proc/video support, which allows it to
compile again.

Again, I messed up the usage, now we are safe from devices being removed.
This fixes a number of error reports from users.

This fixes the kobject messages when disconnecting a usb serial device that
people have been complaining about.

Unfortunately, usb_set_configuration() is widely mis-used as a
lightweight device reset.  That's trouble because setting a
configuration must sometimes involve things that don't relate
at all to a light reset, and can't be done in contexts like
driver probe() calls.

This patch updates most usb_set_configuration() users to use a call
that provides more appropriate functionality:

  - Adds a new usb_reset_configuration() call, which never needs
    to change very much usbcore state.

  - Uses it to replace most usb_set_configuration() calls, in
    many serial drivers, hisax, dvb, irda, and so on.

  - Modifies usb_reset_device() so it issues the control request
    directly.  It's both more of a reset (hides a USB reset) and
    less of one (altsettings are unchanged).

  - Makes usbfs return the error code instead of discarding it.

Once this goes in, then usb_set_configuration() can be made to
work properly (including from sysfs).

This resolves the annoyance that dabusb claims devices
it shouldn't (and hotplugs for them), because of wrongly
including the device IDs used by an21xx devices that don't
have an ID prom.  Mostly affects developers.

Deti OK'd such a patch ages ago.

this can oops.

  - check for mem alloc failure

  - fail if second interface is already claimed

  - update commentary

this function races with itself, doesn't return errors and races with
releasing interfaces. This patch fixes it by changing the function
prototype, introducing locking and having a correct order in
releasing interfaces.

  - API change to check errors in usb_driver_claim_interface and
    fix a race condition between releasing and reclaiming an interface

it seems that I've broken usblp. This reverts to the old
behaviour. Please apply.

  - revert to old timeout handling

  - in interrupt usb_submit_urb must use GFP_ATOMIC

The following patch has been floating around forever.  It is required
for several ARM framebuffer drivers, and several other drivers.  James
has indicated that this is the correct fix back in May.

This provides the necessary infrastructure for PowerMac specific drivers
(and actually some Open Firmware platform drivers on non-PowerMacs as
well provided somebody port them) to be properly probed & referenced via
the new driver model and be part of sysfs.

As-is, this patch doesn't break anything nor change any driver.  I'll
send you individual driver patches as I clean them up & get them tested
on as many machines as possible, though I don't expect much problems.

While reviewing my 2.4 backport of the 2.6 cpu capabilities (including
the Via RNG support), Mikael Pettersson noticed a bug in both my
backport, and 2.6:  when NCAPINTS (x86_capability array size) is
increased, one must adjust the offset in arch/i386/kernel/head.S also.

This makes the HISAX ST5481 driver build again with 2.6.0-test3 where
the usb_host_config structure has changed.

some small clean-ups: do correct errorhandling

added WDIOC_SETTIMEOUT and WDIOC_GETTIMEOUT ioctls
made timeout (the emulated heartbeat) a module_param
made the keepalive ping an internal subroutine

add CONFIG_WATCHDOG_NOWAYOUT support
changed watchdog_info to correctly reflect what the driver offers
added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS and WDIOC_SETOPTIONS ioctls
use module_param

cleanup comments and trailing spaces
eliminate extra spin_unlock
add KERN_* tags to printks
added extra printk's to report what problem occured

some small clean-ups (use PFX + report default timeout as it's value in the MODULE_PARM_DESC)

some last clean-ups

added extra printk's to report what problem occured

make wdt_stop and wdt_start module params

report default timeout as a number

general cleanup of trailing spaces and comments
fix possible wdt_is_open race
add KERN_* to printk's
changed watchdog_info to correctly reflect what the driver offers
added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS, WDIOC_SETTIMEOUT, WDIOC_GETTIMEOUT, and WDIOC_SETOPTIONS ioctls
made timeout (the emulated heartbeat) a module_param
made the keepalive ping an internal subroutine
added MODULE_AUTHOR and MODULE_DESCRIPTION info
