This patch adds a driver for SMSC's LAN7500 family of USB 2.0
to gigabit ethernet adapters. It's loosely based on the smsc95xx
driver but the device registers for LAN7500 are completely different.

bridge: Fix br_forward crash in promiscuous mode
It's a linux-next kernel from 2010-03-12 on an x86 system and it
OOPs in the bridge module in br_pass_frame_up (called by
br_handle_frame_finish) because brdev cannot be dereferenced (its set to
a non-null value).
Adding some BUG_ON statements revealed that
BR_INPUT_SKB_CB(skb)->brdev == br-dev
(as set in br_handle_frame_finish first)
only holds until br_forward is called.
The next call to br_pass_frame_up then fails.
Digging deeper it seems that br_forward either frees the skb or passes
it to NF_HOOK which will in turn take care of freeing the skb. The
same is holds for br_pass_frame_ip. So it seems as if two independent
skb allocations are required. As far as I can see, commit
b33084be192ee1e347d98bb5c9e38a53d98d35e2 ("bridge: Avoid unnecessary
clone on forward path") removed skb duplication and so likely causes
this crash. This crash does not happen on 2.6.33.
I've therefore modified br_forward the same way br_flood has been
modified so that the skb is not freed if skb0 is going to be used
and I can confirm that the attached patch resolves the issue for me.

Since all callers of br_mdb_ip_get need to check whether the
hash table is NULL, this patch moves the check into the function.
This fixes the two callers (query/leave handler) that didn't
check it.

invalidate it. Change this behaviour so we only invalidate it if it

V2: Corrected integer/long conversion.
Some BIOSes return a negative value for the critical trip point.
Especially since Windows 2006...
We currently invalidate the whole thermal zone in this case.
But it may still be needed for cooling, also without critical
trip point.
This patch invalidates the critical trip point if no _CRT
function is found or if it returns negative values, but does
not invalidate the whole thermal zone in this case.

Now that the early _PDC evaluation path knows how to correctly
evaluate _PDC on only physically present processors, there's no
need for the processor driver to evaluate it later when it loads.
To cover the hotplug case, push _PDC evaluation down into the
hotplug paths.

We want this because some BIOS will provide a _PDC even for processors

non-existent tables, which causes problems.

We've renamed the old processor_core.c to processor_driver.c, to
convey the idea that it can be built modular and has driver-like
bits.
Now let's re-create a processor_core.c for the bits needed
statically by the rest of the kernel. The contents of processor_pdc.c
are a good starting spot, so let's just rename that file and
complete our three card monte.

The ACPI processor driver can be built as a module. But it has
pieces of code that should always be built statically into the
kernel.
The plan is for processor_core.c to contain the static bits while
processor_driver.c contains the module-like bits.
Since the bulk of the code in the current processor_core.c is
module-like, first step is to rename the file to processor_driver.c
Next step will re-create processor_core.c and cherry-pick out
the static bits.

Add support for resource windows. This is for bridge resources, i.e.,
regions where a bridge forwards transactions from the primary to the
secondary side. This does not add support for *setting* windows via
the /proc interface.

SuSE added these entries when deploying ACPI in Linux-2.4.
I pulled them into Linux-2.6 on 2003-08-09.
Over the last 6+ years, several entries have proven to be
unnecessary and deleted, while no new entries have been added.
Matthew suggests that they now have negative value, and I agree.

If the ACPI power state can be got both directly and indirectly,
we prefer to get it indirectly.
https://bugzilla.redhat.com/show_bug.cgi?id=531916 describes a
system with a _PSC method for the fan that always returns "on".
There's no benefit in us always requesting the state of the fan
when performing transitions - we want to do everything we can
to ensure that the fan turns on when it should do, not risk
hardware damage by believing the hardware when it tells us the
fan is already on. Given that the Leading Other OS(tm) works fine
on this machine, it seems likely that it behaves in much this way.

There is a race between resume from hibernation and the EC driver
that may result in restoring the hibernation image in the middle of
an EC transaction in progress, which in turn may lead to
unpredictable behavior of the platform.
To remove that race condition, add a helpers for suspending and
resuming EC transactions in a safe way to be executed by the ACPI
platform hibernate pre-restore and restore cleanup callbacks.

Per ACPI spec, _ERG method should be executed before device driver
gets control for hotpluged device. Firmware might do some configuration
there. See http://bugzilla.kernel.org/show_bug.cgi?id=10805. In this
machine, _REG method of docked device will configure cardbus bridge.

Move the in-the-middle-of-file lock variable up to the variable
definition section, the top of the .c file.
