It apparently really confuses some things (Apple keyboard
internal hub for one, but possibly others).

	This tiny bit of the last WE-17 patch was lost between me and
you. I initially decided to wait to resubmit, but Chris Wedgwood
reported that the MadWifi driver needs it. Sorry for not having pushed
harder.
	I recreated this patch, and tested with 2.6.10-rc1, and Chris
tested it with MadWifi. Would you mind pushing that up to Linus ?

Experimented a bit more with mounting a bad ext2 filesystem.

An immediate crash was caused by zero EXT2_BLOCKS_PER_GROUP(sb).
The patch below (relative to 2.6.9) adds a few checks to make sure
that things we divide by are not zero.

There is a similar problem reported by s390 people where we see parent
kobject (directory) going away before child kobject (sub-directory). It
seems kobject code is able to handle this, but not the sysfs. What could
be happening that in sysfs_remove_dir() of parent directory, we try to
remove its contents. It works well with the regular files as it is the
final removal for sysfs_dirent corresponding to the files. But in case
of sub-directory we are doing an extra sysfs_put().  Once while removing
parent and the other one being the one from when sysfs_remove_dir() is
called for the child.

The following patch worked for the s390 people, I hope same will work in
this case also.


o Do not remove sysfs_dirents corresponding to the sub-directory in
  sysfs_remove_dir(). They will be removed in the sysfs_remove_dir() call
  for the specific sub-directory.

This is a relatively small changeset, to address small nagging problems.
Andrew pointed me at the double registration specifically, so I had to do
something about it. At least now Fabio's box won't collapse if he configures
UB by mistake. Also, a few people complained that the help text was
misleading.

I have not done anything about the oops on disconnect which happens to
Martin Schlemmer. It's next. After that I can get to Peter Jones' CD
burning patch and doing resets.

- Fix double kobject registration and eventual oops on unplug if a device
  is not cooperating.
- Add a reference to usb-storage into the configuration help.
- Just upping timeouts fixes my ZIP drive.
- Max out the diag (trace) file size.
- Set capacity to zero in case the media is absent. It works in 2.4.10-rc1.

Looks like kobject_uevent_init is executed before netlink_proto_init and
consequently always fails.  Not cool.

Attached patch switches the initialization over from core_initcall (init
level 1) to postcore_initcall (init level 2).  Netlink's initialization
is done in core_initcall, so this should fix the problem.  We should be
fine waiting until postcore_initcall.

Also a couple white space changes mixed in, because I am anal.

 df_02_bus_rescan_devcies_fix.patch

 bus_rescan_devices() eventually calls device_attach() and thus

separates __bus_for_each_dev() and __bus_for_each_drv(), which don't
do locking themselves, out from the original functions and call them
with read lock in the original functions and with write lock in
bus_rescan_devices().

Add the sysfs path of the physical device to the hotplug event of class
and block devices. This should solve the userspace issue not to know if
the device is a virtual one and the "device" symlink will never be created,
but we sit there and wait for it to show up not knowing when we should
give up.

Also the bus name is added to the hotplug event, so we don't need to
reverse lookup in the /sys/bus/* directory which bus our physical
device belongs to. This is e.g. the value matched against the BUS= key,
that may be used in an udev rule.

The routine ext2_readdir() will, when reading a directory page
returns an error, try the next page, without reporting the
error to user space. That is bad, and the patch below changes that.

In my case the filesystem was damaged, and ext2_readdir wanted
to read 60000+ pages and wrote as many error messages to syslog
("attempt to access beyond end"), not what one wants.

[no doubt a similar patch is appropriate for ext3]

a comment about the chip, with no support. Patch is against 2.6.9 but is
pretty minimal.

This patch updates the serial gadget driver:

 - The bulk is Al Borcher's version 2.0 updates:

     * Use the new utilities to build config descriptors from tables.

     * Add CDC ACM support, which brings lots of goodness including
       interop with Windows.

     * Work better given PXA 25x hardware automagic.

 - I have a few minor tweaks.

     * Match the recent tty API change:  from_user is gone!!

     * Define new product ID for the CDC ACM version, so Windows
       registry won't get confused by the non-ACM version.

     * Add OTG descriptor

     * Allocates packet buffers more efficiently on platforms like
       OMAP: use kmalloc not the dma-coherent allocator.

Al has some docs on how to talk to Windows this, including an INF file.

This is the second of the patches from Dale Farnsworth to
support OHCI implementations that use big-endian byte sex
for registers ... all register accesses changed, that's why
it's so large.  (It also includes part of an update from
his third patch, so that it compiles/runs by itself.)

This patch adds support to the OHCI code for big-endian controllers,
maintaining the existing little-endian support.  This is done using
the following transforms:

        ohci_readl(p)   --> ohci_readl(ohci, p)
	writel(v, p)    --> ohci_writel(ohci, v, p)

	cpu_to_le16(v)  --> cpu_to_hc16(ohci, v)
	cpu_to_le16p(v) --> cpu_to_hc16p(ohci, v)
	cpu_to_le32(v)  --> cpu_to_hc32(ohci, v)
	cpu_to_le32p(v) --> cpu_to_hc32p(ohci, v)

	le16_to_cpu(v) --> hc16_to_cpu(ohci, v)
	le16_to_cpup(v) --> hc16_to_cpup(ohci, v)
	le32_to_cpu(v) --> hc32_to_cpu(ohci, v)
	le32_to_cpup(v) --> hc32_to_cpup(ohci, v)

	OHCI_FRAME_NO(ohci->hcca) --> ohci_frame_no(ohci)

There's no runtime penalty except for systems configured to handle
both byteorders at the same time.
