The following patch fixes incorrect dependencies (as far as I can see)
for the SCx200 modules. A similar patch (with even more fixes) is also
needed for Linux 2.4, and will be part of my next wave to Marcelo. Note
that I don't have the necessary hardware to actually test anything, but
a quick look at the code doesn't leave much place for doubt IMHO.

This patch drops bus scan from i2c-algo-ite and i2c-ibm_iic. It also
removes the incomplete and broken SLO_IO stuff from i2c-algo-ite.

This fixes byte writes (used by the eeprom driver) in the i2c-amd756
driver.  It is similar to recent fixes for the i2c-amd8111 and
i2c-nforce2 drivers.

Tested by me.

This patch is based on the lm_sensors project CVS, from revisions 1.45 and 1.1
of lm75.c and lm75.h, respectively.

The patch fixes the conversion routines (according to datasheet) and moves
them into a header file - as these conversions can be used by several drivers
which emulate LM75s as subclients.  Also, temps are now reported in 1/1000 C
in sysfs as per documentation.

This patch is from the lm_sensors project CVS, from this revision:

	1.44 (mds) remove initialization of limits by driver

It is better to set these limits by a combination of /etc/sensors.conf
and 'sensors -s'; "mechanism not policy."

This patch is from the lm_sensors project CVS, from this revision:

	1.111 (mds) remove initialization of limits by driver

It is better to set these limits by a combination of /etc/sensors.conf
and 'sensors -s'; "mechanism not policy." And what's not to like about
a patch that removes 163 lines?

This patch improves chip detection.  It was forward ported from the
lm_sensors project CVS, from these revisions:

	1.104 (Khali) Enhance chip detection (stricter).
	1.108 (Khali) Fix W83627HF detection.

This patch restores support for the AMD8111 in the i2c-amd756 driver.

Credits go to Philip Pokorny for the original patch. I tweaked it a bit.

This isn't a bug fix and can be delayed until after 2.6.0 if you want.

This patch fixes i2c_smbus_write_byte() being broken for i2c-amd8111.
This causes trouble when that module is used together with eeprom (which
is also in 2.6). We have had no report so far, but the problem is
similar to the one addressed by a recent patch to i2c-nforce2.

Credits go to Hans-Frieder Vogt for finding and fixing the problem. Mark
D. Studebaker found and fixed the original problem in i2c-nforce2.

This is a serious bug fix, and I believe you shouldn't wait too long
before applying it.

This fixes a bug in the qla1280 driver where it would leave a pointer to
an on the stack completion event in a command structure if
qla1280_mailbox_command fails.  The result is that the interrupt handler
later tries to complete() garbage on the stack.  The mailbox command can
fail if a device on the bus decides to lock up etc.

I just found Yet Another Bug in scsi_ioctl - CDROM_SEND_PACKET puts a
kernel pointer in hdr->cmdp, where sg_io() expects to find user address.
This worked up until recently because of the memcpy bug, but now it
doesn't because we do the proper copy_from_user(). 

This fix undoes the user copy code from sg_io, and instead makes the
SG_IO ioctl copy it locally.  This makes SG_IO and CDROM_SEND_PACKET
agree on the calling convention, and everybody is happy. 

I've tested that both

   cdrecord -dev=/dev/hdc -inq

and

   cdrecord -dev=ATAPI:/dev/hdc -inq

works now.  The former will use SG_IO, the latter CDROM_SEND_PACKET (and
incidentally would work in both 2.4 and 2.6, if it wasn't for
CDROM_SEND_PACKET sucking badly in 2.4).

From Jon Burgess:

  There is a problems with blank DVD media using the ide-cd driver.

  When we attempt to read the blank disk, the drive responds to the read
  request by returning a "blank media" error.  The kernel doesn't have
  any special case handling for this sense value and retries the request
  a couple of times, then gives up and does a bus reset and disables DMA
  to the device.

  Which obviously doesn't help the situation.

  The sense key value of 8 isn't listed in ide-cd.h, but it is listed in
  scsi.h as a "BLANK_CHECK" error.

  This trivial patch treats this error condition as a reason to abort
  the request.  This behaviour is the same as what we do with a blank CD-R.

  It looks like the same fix might be desired for 2.4 as well, although
  is perhaps not so important since scsi-ide is normally used instead.

 1/ make sure raid5 doesn't try to handle multiple overlaping
    requests at the same time as this would confuse things badly.
    Currently it justs BUGs if this is attempted.
 2/ Fix a possible data-loss-on-write problem.  If two or
    more bio's that write to the same page are processed at the
    same time, only the first was actually commited to storage.
 3/ Fix a use-after-free bug.  raid5 keeps the bio's it is given
    in linked lists when more than one bio touch a single page.
    In some cases the tail of this list can be freed, and
    the current test for 'are we at the end' isn't reliable.
    This patch strengths the test to make it reliable.

Petr Vandrovec noticed a problem where the thread group leader
would not be properly reaped if the parent of the thread group
was ignoring SIGCHLD, and the thread group leader had exited
before the last sub-thread.

Fixed by Ingo Molnar.

This time we have a SMP memory ordering issue in prepare_to_wait(),
where we really need to make sure that subsequent tests for the
event we are waiting for can not migrate up to before the wait
queue has been set up.

In 2.5.x, the BKL was pushed from vfs_readdir() into the filesystem
specific functions.  But only the unlock_kernel() made it into the HPFS
code, lock_kernel() got lost on the way.  This rendered the filesystem
unusable.

This adds the missing lock_kernel().  It's been tested by Timo Maier who
also reported the problem earlier today.

The previous scsi_ioctl.c patch didn't cleanup the buffer/bio in the
error case. 

Fix it by copying the command data earlier.

corruption on SMP because of another CPU still accessing a waitqueue
even after it was de-allocated.

Use a careful version of the list emptiness check to make sure we
don't de-allocate the stack frame before the waitqueue is all done.

visor.c defines one empty slot in USB ids table that can be filled in at
runtime using module parameters. file2alias generates catch-all alias for it:

alias usb:v*p*dl*dh*dc*dsc*dp*ic*isc*ip* visor

patch adds the same sanity check as in depmod to scripts/file2alias.

This patch fixes the bug where running ppp over a ttyUSB device would fail.

This patch was integrated by you in 2.4 six months ago.  Unfortunately
it never got into 2.5.  Without it you can end up with crashes such
as http://bugs.debian.org/218670

apart from locking bugs, there are other races. This fixes one with
signal delivery. The signal should be delivered _before_ the reciever
is woken.

this fixes two instances of GFP_KERNEL from completion handlers.

After a bit of mucking around (and possibly finding a bug with debian's
libusb/xsane/hotplug interaction, nothing seems to run
/etc/hotplug/usb/libusbscanner and thus only root can scan, anyone whose
got this working please let me know), the problem does not exist if I
only use  libusb xsane.

How about the following:

This patch fixes some obvious errors in the jumpshot and datafab drivers.

This should close out Bugzilla bug #1408

James reported a bug in scsi_ioctl.c where it mem copies a user pointer
instead of using copy_from_user(). I inadvertently introduced this one
when getting rid of CDROM_SEND_PACKET. Here's a trivial patch to fix it.

TCP IPV6 ->hash() method should not grab a socket reference.

If a device can't be configured, the current test9 code forgets
to clean it out of sysfs.  This resolves that issue, so the retry
in usb_new_device() stands a chance of working.

The enumeration code still doesn't handle such errors well, but
at least this way that hub port can be used for another device.
