OK, I'm having a look here; its all new to me so bear with me.

blkdev_open() calls
  do_open(bdev, ...,BD_MUTEX_NORMAL) and takes
    mutex_lock_nested(&bdev->bd_mutex, BD_MUTEX_NORMAL)

then something fails, and we're thrown to:

out_first: where
    if (bdev != bdev->bd_contains)
      blkdev_put(bdev->bd_contains) which is
        __blkdev_put(bdev->bd_contains, BD_MUTEX_NORMAL) which does
          mutex_lock_nested(&bdev->bd_contains->bd_mutex, BD_MUTEX_NORMAL) <--- lockdep trigger

When going to out_first, dbev->bd_contains is either bdev or whole, and
since we take the branch it must be whole. So it seems to me the
following patch would be the right one:

Recently a patch was added for preliminary suspend/resume handling on
!PPC_PMAC.  However, this broke both suspend and firewire on powerpc
because it saves the pci state after the device has already been disabled.

This moves the save state to before the pmac specific code.

c06aad854f [PATCH] dm: Fix deadlock under high i/o load in raid1 setup.
On an nForce4-equipped machine with two SATA disk in raid1 setup using dmraid,
we experienced frequent deadlock of the system under high i/o load.  'cat
/dev/zero > ~/zero' was the most reliable way to reproduce them: Randomly
after a few GB, 'cp' would be left in 'D' state along with kjournald and
kmirrord.  The functions cp and kjournald were blocked in did vary, but
kmirrord's wchan always pointed to 'mempool_alloc()'.  We've seen this pattern
on 2.6.15 and 2.6.17 kernels.  http://lkml.org/lkml/2005/4/20/142 indicates
that this problem has been around even before.

So much for the facts, here's my interpretation: mempool_alloc() first tries
to atomically allocate the requested memory, or falls back to hand out
preallocated chunks from the mempool.  If both fail, it puts the calling
process (kmirrord in this case) on a private waitqueue until somebody refills
the pool.  Where the only 'somebody' is kmirrord itself, so we have a
deadlock.

I worked around this problem by falling back to a (blocking) kmalloc when
before kmirrord would have ended up on the waitqueue.  This defeats part of
the benefits of using the mempool, but at least keeps the system running.  And
it could be done with a two-line change.  Note that mempool_alloc() clears the
GFP_NOIO flag internally, and only uses it to decide whether to wait or return
an error if immediate allocation fails, so the attached patch doesn't change
behaviour in the non-deadlocking case.  Path is against current git
(2.6.18-rc4), but should apply to earlier versions as well.  I've tested on
2.6.15, where this patch makes the difference between random lockup and a
stable system.

66a377c504 [DCCP]: Fix CCID3
This fixes CCID3 to give much closer performance to RFC4342.

CCID3 is meant to alter sending rate based on RTT and loss.

The performance was verified against:
http://wand.net.nz/~perry/max_download.php

For example I tested with netem and had the following parameters:
Delayed Acks 1, MSS 256 bytes, RTT 105 ms, packet loss 5%.

This gives a theoretical speed of 71.9 Kbits/s. I measured across three
runs with this patch set and got 70.1 Kbits/s. Without this patchset the
average was 232 Kbits/s which means Linux can't be used for CCID3 research
properly.

I also tested with netem turned off so box just acting as router with 1.2
msec RTT. The performance with this is the same with or without the patch
at around 30 Mbit/s.

954c0b7cd5 [PATCH] PCI: use PCBIOS as last fallback
there was a change in 2.6.17 which affected the order in which the PCI
access methods are probed.  this gives regressions on some machines with
broken BIOS.  the problem is that PCBIOS sometimes reports last bus wrong,
leaving cardbus non-funcational.  previously those system worked fine with
direct access.

The patch changes the PCI init code to have PCBIOS as last fallback, yet
the PCBIOS code still has to run first to set pcibios_last_bus to the value
reported by the BIOS.  this is needed in case legacy PCI probing
(arch/i386/pci/legacy.c) is used to detect peer busses.  using direct
access if available fixes the cardbus problems.

    timeout errors on some motherboards
 2) Fix the exit paths in the bank1 sensor type detect code to always
    restore the original settings even on an error. Without this our
    special test settings could remain seriously confusing the system
    BIOS's setup menu.

Both are very much related and are must haves, to avoid messing up the
uguru CMOS settings.

Detailed changes:
- Much improved timeout / wait for status handling. Many thanks to Sunil
  Kumar, for all his testing, ideas and patches! The code now first busy
  waits, polling the uguru for the expected status as this usually
  succeeds pretty quickly (within 90 reads). To avoid unnecessary CPU burn
  in timeout conditions, the amount of busy waiting has been halved from
  previous versions (120 tries instead of 250). This is not a problem,
  because this version goes to sleep after 120 attemps for 1 jiffy and
  then tries again, it does this sleep and try again 5 times before
  finally giving up. This (almost?) completly removes the timeout errors
  some people have seen regulary. Apparently some older uguru versions
  sometimes are distracted for a (relatively) long time. This solves this.
- These timeout errors not only occur in the sending address part of
  reading the uguru but also in the wait for read state, so errors in
  this state are now handled as retryable just like send address state
  errors and are only logged and reported to userspace if 3 executive
  tries fail.
- Fix a very nasty bug in the bank1 sensor type detection code, where it
  would not restore the original settings in any of the error paths!
- Since not successfully restoring the original settings can seriously
  confuse the system BIOS (hang when entering the relevant setup menu),
  we now try restoring them 3 times before giving up.

4801bc25f3 [PATCH] i2c: tps65010 build fixes
The tps65010.c driver in the main tree never got updated with
build fixes since the last batch of I2C driver changes; and the
genirq trigger flags were updated wierdly too.

This also includes a minor tweak to reduce the frequency used to
poll for unplug-the-AC-power on the TPS chips that don't provide
relevant IRQs.  It _would_ be nice to sense whether there's even
a battery, but that'd normally be an HDQ/1-wire interface to a
smart battery, and such APIs aren't standardized.

0db99e3359 [SCSI] fix scsi_send_eh_cmnd regression
The callers of scsi_send_eh_cmnd are setting the cmnd buffer,
and then scsi_send_eh_cmnd is copying that updated buffer to
the old_cmnd variable. Then after the command runs, we end up
copying that old_cmnd var which has the new cmnd to the scsi
command buffer. When this command gets recent, all types of fun
things happen like getting TUR or START_STOP commands with
data and scatterlists.

This patch made against scsi-rc-fixes, has the callers of
scsi_send_eh_cmnd pass in the command so scsi_send_eh_cmnd
can do the right thing. This should go into 2.6.18 since this
fixes a regression added when we removed some of the scsi_cmnd
fields and replaced them with local variables.

9c06938aa4 [SCSI] qla2xxx: Correct PLOGI retry logic.
Original code attempts to retry PLOGIs to fcports that are
FCP_TARGETs only.  If the driver never performed a successful
PLOGI/PRLI, the port-type would never be assigned, and the
relogin logic would silently drop the request (and thus the port
would not be recognized and registered).

The fix is relatively straightforward, drop the FCP_TARGET-only
check.

b2155d0417 [SCSI] sg: fix incorrect page problem
There's a problem where sg is executing a ->nopage operation on a
compound page, it actually calls get_page() on the first page in the
compound rather than the page which is being mapped.  The fix is to
select the correct page by indexing into the compound.
