Here is a proposed patch that cleanups the fan_div code from w83781d.
The original code was obviously taken from the 2.4 driver, but the way
things were done in 2.4 do not make any sense anymore (because we now
have a single value per interface file).

Since fan divisor bits are spread over three different regs with various
bitmask manipulations, I don't think it makes much sense to have a
single function as we do in most other cases. Having three different
functions makes more sense, although they are of course similar. The
size increment is only 581 bytes, I don't think its a problem since it
also makes the code much more efficient and readable too IMHO.

I agree that the original code was working - it was simply doing far too
much work each time one would want to change a fan divisor.

Originally, I took a look at the code because I wanted to fix the fact
that changing fan divisors breaks fan mins. But it looked like a good
cleanup before doing that was required. Once this patch will have been
accepted, I'll work on the other one.

I've tested my patch successfully on a W83781D and an AS99127F rev.1.
Note that this means that one part of the code wasn't tested, because
these are the two chips of the family that do not support divisors
greater than 8. If anyone can test it, please do.

Quoting myself:

Here is a proposed patch that does this. Comments welcome.

Please accept this temporary fix for the class issue. I'd like users of
the i2c-ali1535, i2c-sis5595 and i2c-via driver to be able to use
sensors as soon as possible, even if we have not yet determined what our
policy WRT classes should be.

Thanks.

BTW, don't you think I2C_ADAP_CLASS_SMBUS is a misnomer? It's about
hardware monitoring, not the SMBus protocol. I'd say
I2C_ADAP_CLASS_HWMON or I2C_ADAP_CLASS_SENSORS would have been more
appropriate (although it may be a bit late for a change...)

prosavage_remove() is called during init, so it shouldn't be
marked as exit code.  (It matters when CONFIG_HOTPLUG=n.)

This patch updates the sysfs names of the w83627hf driver
to match the new standard.  The patch applies on top of
one recently applied to your tree [1].  I have tested it
using a w83627thf & the latest lm_sensors CVS.  Please apply.

i2c_use_client() contains a bogosity.  If i2c_inc_use_client() returns
success, i2c_use_client() returns an error.  If i2c_inc_use_client()
fails, i2c_use_client() might succeed.

Fix it so that (a) we get the correct sense between these two functions,
and (b) propagate the error code from i2c_inc_use_client(), rather than
making our own one up.

Looks like i2c-dev suffers the same problem with dev_dbg as i2c-core did
twice. Here is a patch that fixed a oops I and another user were
experiencing when running sensors-detect.

The attached patch updates wanXL card driver. Please apply to Linux 2.6.
Thanks.

Changes:
* fixed initialization kernel panic, introduced with recent alloc_netdev()
  wan patch,
* wanxl_rx_intr() port# now checked before accessing port structure,
* cleanups etc.

Use %08llx for a dma_addr_t, not the recently-added %llx.

The carmel driver will want to use this rather
than muck around in queue internals directly.

Declarations come before statements, please.

Current gcc warns about this too, bless them:

Fix the description of the IO ports for the IDE primary and secondary

From: Aneesh Kumar KV <aneesh.kumar@digital.com>

We need to set the tasks's exit code prior to waking it, not afterwards.

Acked by rth.

Dave Kleikamp <shaggy@austin.ibm.com> points out a race between
nobh_prepare_write() and end_buffer_read_sync().  end_buffer_read_sync()
calls unlock_buffer(), waking the nobh_prepare_write() thread, which
immediately frees the buffer_head.  end_buffer_read_sync() then calls
put_bh() which decrements b_count for the already freed structure.  The
SLAB_DEBUG code detects the slab corruption.

We fix this by giving nobh_prepare_write() a private buffer_head end_o
handler which doesn't touch the buffer's contents after unlocking it.

From: Eric Sandeen <sandeen@sgi.com>

Several functions in buffer.c are using unsigned long where they should be
using sector_t.

Also, use pgoff_t in several places so it is easier to tell what is beingused
as a pagecache index, what is being used as a disk index and what is being
used as an offset-into-page.

If a large pci_alloc_consistent() GFP_ATOMIC allocation fails this driver's
recovery code will call emu10k1_wavein_close() far earlier than it should: it
goes splat in emu10k1_timer_uninstall().

Fix it by simply removing that call: we haven't allocated any resources yet
anyway.

Note that one of the callers of emu10k1_wavein_open(), emu10k1_audio_read()
will sit there stupidly retrying the open.  But it has a sleep in there so
something might eventually give way.

drivers/message/i2o/i2o_block.c:

 - corrected the initialization sequence of the request queues.

 - added initialization to queue spinlocks.

 - release device in i2o_scan because else the device could not be queried.

 - i2o_block event threads wait on signal KILL but signal TERM was sent.

drivers/message/i2o/i2o_core.c:

 - set the HRT length to 0 at initialization, to avoid calling free on
   unallocated memory.

 - i2o_core event threads wait on signal KILL but signal TERM was sent.

 - added a limit of 3 tries to get the HRT from the controller.

 - removed the dpt parameter, which was used to force DPT controllers get
   handled by the i2o driver.  Now all available i2o controllers will be
   handled by this driver.

drivers/message/i2o/i2o_scsi.c:

 - beautifying of printk calls.

 - added scsi_unregister to properly clean up on module unload.

drivers/message/i2o/Kconfig:

 - added help for i2o_block and i2o_scsi to describe the differences between
   the two drivers.

include/linux/i2o-dev.h:

 - cleaned typo "tate" into "state".

include/linux/i2o.h:

 - removed defines from i2o_block and insert it here.

This patch fixes a bug in the v4l1-compat module and makes it pass the

find_group_other looks buggy for ext2 and ext3 in 2.6, it can cause -ENOSPC
errors when the fs has plenty of free room.

To hit the bug, you need a filesystem where:

parent_group has no free blocks (but might have free inodes) Every other
group with free inodes has no free blocks.

That gets you down to the final linear search in find_group_other.  The
linear search has two bugs:

group = parent_group + 1; means we start searching at parent_group + 2
because the loop increments group before using it.

for(i = 2 ; i < ngroups ; i++) means we don't search through all the
groups.

The end result is that parent_group and parent_group + 1 are not checked
for free inodes in the final linear search.  ext3 has the same problem.

Converts the mm_context_t on ppc64 to be a struct.  This lets us separate
the low_hpages flag into a separate field rather than folding it into the
actual context id.  That makes things neater, since the flag is
conceptually separate and has, for example, should be propogate across a
fork whereas the context ID obviously isn't.  The mm_context_id is the only
place to put arch-specific information in the mm_struct.

We've changed gss_get_mic to write mic in place instead of kmalloc'ing new
memory for it; change must also be reflected in server side code.
