Update 3 more new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. These
video drivers aren't used yet so converting them is trivial.

As the old driver_name/type matching scheme is going away soon, change
the dummy device mechanism to use the new matching scheme.
This has the downside that dummy i2c clients can no longer choose
their name, they'll all appear as "dummy" in sysfs and in log
messages. I don't think it is a problem in practice though, as there
is little reason to use these i2c clients to log messages.

The i2c_sibyte_add_bus() function is not called, nor meant to, from

The frequency may have been once hardcoded to 100 kHz, but currently it is
passed as an argument to i2c_sibyte_add_bus(), so update the comment to
match code. While at it, reformat a nearby comment for consistency. No
functional changes.

We had a report that running sensors-detect on a Sapphire AM2RD790
motherbord killed the CPU. While the exact cause is still unknown,
I'd rather play it safe and prevent any access to the SMBus on that
machine by not letting the i2c-piix4 driver attach to the SMBus host
device on that machine. Also blacklist a similar board made by DFI.

Per the PIIX4 errata, there maybe a delay between setting the
start bit in the Smbus Host Controller Register and the transaction
actually starting. If the driver doesn't delay long enough, it
may appear that the transaction is complete when actually it
hasn't started, this may lead to bus collisions.
While 1 ms appears to be enough for most chips, the ServerWorks CSB5
wants 2 ms.

Alter the mpc i2c driver to use the NO_IRQ symbol instead of the constant
zero when checking for valid interrupts. NO_IRQ=-1 on ppc and NO_IRQ=0 on
powerpc so the checks against zero are not correct.

This fixes some two minor clk issues.
The first is a comparison where a byte will probably wrap around to 0 instead of being saturated to 255, shouldn't be triggered very often but need fixing.
The second is an attempt by the driver to adjust MCLK down to the maximum frequency according to the spec, so we don't accidentally overclock the PL18x block. None of the mach-{versatile|integrator|lh7a40x} that use it in-tree seem to have a problem with this (all are well below 100MHz, typically 33MHz), but some day there will be a problem.
This is not applied on top of the earlier mmci patch for race condition but rather a clean 2.6.25, but I guess it applies without major protests anyway.

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=10577
I was unable to access a computer containing an Intel EtherExpress 16 network
card using IPv6.
I traced this to failure of neighbour discovery. When I used an "ip -6 neigh
add" command, on the computer attempting access, to insert a binding between
the IPv6 address of the computer with the Intel EtherExpress 16 network card
and the card's ethernet address, I was able to access that computer using
IPv6.
Neighbour discovery requires working multicast. The driver sources file
eexpress.c contains an approximately 30 line function eexp_setup_filter used
when loading multicast addresses.
I found 3 problems in this function
1) It wrote the number of multicast addresses to the card instead of the
number of bytes in the multicast addresses.
2) When loading multiple multicast addresses it loaded the first one
provided multiple times instead of loading each one once.
3) The setting of pointer 'data' from 'dmi->dmi_addr' occured before the
test for the error situation of 'dmi' being NULL.
Correcting these problems allows the computer with the Intel EtherExpress 16
network card to found by IPv6 neighbour discovery.
p.s. There is some information on the Intel EtherExpress 16 at
http://www.intel.com/support/etherexpress/vintage/sb/cs-013500.htm

The ethernet card 3c980-TX needs a mdio_sync() to initialize the ethernet
properly. This is forced by adding an EXTRA_PREAMBLE to its drv_flags.
Without this, the driver did not reconnect after a link loss.

Move mv643xx_eth's static state (ethernet register block base address
and MII management interface spinlock) into a struct hanging off the
shared platform device. This is necessary to support chips that
contain multiple mv643xx_eth silicon blocks.

This patch adds support for the BM PHY, a new PHY model being used
on ICH9-based implementations.
This new PHY exposes issues in the ICH9 silicon when receiving
jumbo frames large enough to use more than a certain part of the
Rx FIFO, and this unfortunately breaks packet split jumbo receives.
For this reason we re-introduce (for affected adapters only) the
jumbo single-skb receive routine back so that people who do
wish to use jumbo frames on these ich9 platforms can do so.
Part of this problem has to do with CPU sleep states and to make
sure that all the wake up timings are correctly we force them
with the recently merged pm_qos infrastructure written by Mark
Gross. (See http://lkml.org/lkml/2007/10/4/400).
To make code read a bit easier we introduce a _IS_ICH flag so
that we don't need to do mac type checks over the code.

This patch fixes uli526x driver's issues on a PowerPC boards: uli chip
is unable to receive the packets.
It appears that send_frame_filter prepares the setup frame in the
endianness unsafe manner. On a big endian machines we should shift
the address nibble by two bytes.

The firmware on MPC8610HPCD boards enables ULI ethernet and leaves it
in some funky state before booting Linux. For drivers, it's always good
idea to (re)initialize the hardware prior to requesting interrupts.
This patch fixes the following oops:

ucc_geth didn't have anything marked as __iomem. It was also inconsistent
with its use of in/out accessors (using them sometimes, not using them other
times). Cleaning this up cuts the warnings down from hundreds to just over a
dozen.

During sparse cleanup, found a locking bug. Some of the sysfs functions were
acquiring a lock, and then returning in the event of an error. We rearrange
the code so that the lock is released in error conditions, too.

bonding / ipv6: no addrconf for slaves separately from master
two steps were rearranged in the enslavement process: netdev_set_master
is now before the call to dev_open to open the slave.
This patch updates the error cases and unwind process at the
end of bond_enslave to match the new order. Without this patch, it is
possible for the enslavement to fail, but leave the slave with IFF_SLAVE
set in its flags.

The sysfs layer has an internal protection, that ensures, that
all the process sitting inside ->sore/->show callback exits
before the appropriate entry is unregistered (the calltraces
are rather big, but I can provide them if required).
On the other hand, bonding takes rtnl_lock in
a) the bonding_store_bonds, i.e. in ->store callback,
b) module exit before calling the sysfs unregister routines.
Thus, the classical AB-BA deadlock may occur. To reproduce run
# while :; do modprobe bonding; rmmod bonding; done
and
# while :; do echo '+bond%d' > /sys/class/net/bonding_masters ; done
in parallel.
The fix is to move the bond_destroy_sysfs out of the rtnl_lock,
but _before_ bond_free_all to make sure no bonding devices exist
after module unload.
