Implement the framework for binding physical devices
with ACPI devices. A physical bus like PCI bus
should create a 'acpi_bus_type', with:
.find_device:
For device which has parent such as normal PCI devices.
.find_bridge:
It's for special devices, such as PCI root bridge
or IDE controller. Such devices generally haven't a
parent or ->bus. We use the special method
to get an ACPI handle.

Here is a proposed Kconfig update for the new max6875 i2c chip driver.
Signed-off-by: Jean Delvare <khali@linux-fr.org>
Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
After a careful code analysis on the new max6875 driver
(drivers/i2c/chips/max6875.c), I have come to the conclusion that this
driver may cause EEPROM corruptions if used on random systems.
The EEPROM part of the MAX6875 chip is accessed using rather uncommon
I2C sequences. What is seen by the MAX6875 as reads can be seen by a
standard EEPROM (24C02) as writes. If you check the detection method
used by the driver, you'll find that the first SMBus command it will
send on the bus is i2c_smbus_write_byte_data(client, 0x80, 0x40). For
the MAX6875 it makes an internal pointer point to a specific offset of
the EEPROM waiting for a subsequent read command, so it's not an actual
data write operation, but for a standard EEPROM, this instead means
writing value 0x40 to offset 0x80. Blame Philips and Intel for the
obscure protocol.
Since the MAX6875 and the standard, common 24C02 EEPROMs share two I2C
addresses (0x50 and 0x52), loading the max6875 driver on a system with
standard EEPROMs at either address will trigger a write on these
EEPROMs, which will lead to their corruption if they happen not to be
write protected. This kind of EEPROMs can be found on memory modules
(SPD), ethernet adapters (MAC address), laptops (proprietary data) and
displays (EDID/DDC). Most of these are hopefully write-protected, but
not all of them.
For this reason, I would recommend that the max6875 driver be
neutralized, in a way that nobody can corrupt his/her EEPROMs by just
loading the driver. This means either deleting the driver completely, or
not listing any default address for it. I'd like this to be done before
2.6.13-rc1 is released.
Additionally, the max6875 driver lacks the 24RF08 corruption preventer
present in the eeprom driver, which means that loading this driver in a
system with such a chip would corrupt it as well.
Here is a proposed quick patch addressing the issue, although I wouldn't
mind a complete removal if it makes everyone feel safer. I think Ben
has plans to replace this driver by a much simplified one anyway.

Currently hid-core follows the same code path for input reports
regardless of whether they are a result of interrupt transfers or
control transfers. That leads to interrupt events erroneously being
reported to hiddev for regular control transfers.
Prior to 2.6.12 the problem was mitigated by the fact that
reporting to hiddev is supressed if the field value has not changed,
which is often the case. Said filtering was removed in 2.6.12-rc1 which
means any input reports fetched via control transfers result in hiddev
interrupt events. This behavior can quickly lead to a feedback loop
where a userspace app, in response to interrupt events, issues control
transfers which in turn create more interrupt events.
This patch prevents input reports that arrive via control transfers from
being reported to hiddev as interrupt events.

Lots of this patch is trivial code cleanups (static vars were being
intialized to 0, etc).
There's also some fixes for ISO transmits (max buffer handling).
Aswell, we have a few fixes to disable IRM capabilites correctly. We've
also disabled, by default some generally unused EXPORT symbols for the
sake of cleanliness in the kernel. However, instead of removing them
completely, we felt it necessary to have a config option that allowed
them to be enabled for the many projects outside of the main kernel tree
that use our API for driver development.
The primary reason for this patch is to revert a MODE6->MODE10 RBC
conversion patch from the SCSI maintainers. The new conversions handled
directly in the scsi layer do not seem to work for SBP2. This patch
reverts to our old working code so that users can enjoy using Firewire
disks and dvd drives again.
We are working with the SCSI maintainers to resolve this issue outside
of the main kernel tree. We'll merge the patch once the SCSI layer's
handling of the MODE10 conversion is working for us.

This is part of the grand scheme to eliminate the qlen
member of skb_queue_head, and subsequently remove the
'list' member of sk_buff.
Most users of skb_queue_len() want to know if the queue is
empty or not, and that's trivially done with skb_queue_empty()
which doesn't use the skb_queue_head->qlen member and instead
uses the queue list emptyness as the test.
