eeepc-laptop: enable camera by default
If we leave the camera disabled by default, userspace programs (e.g.
Skype, Cheese) leave the user out in the cold saying that the machine
"has no camera." Therefore, it's better to enable camera by default and
let people who really don't want it just disable the thing.
To reduce power usage you should enable USB autosuspend:

ACPI: Rename ACPI processor device bus ID
Some BIOS re-use the same processor bus id
in different scope:
\_SB.SCK0.CPU0
\_SB.SCK1.CPU0
But the (deprecated) /proc/acpi/ interface
assumes the bus-id's are unique, resulting in an OOPS
when the processor driver is loaded:
WARNING: at fs/proc/generic.c:590 proc_register+0x148/0x180()
Hardware name: Sunrise Ridge

Rename the processor device bus id. And the new bus id will be
generated as the following format:
CPU+ CPU ID
For example: If the cpu ID is 5, then the bus ID will be "CPU5".
If the CPU ID is 10, then the bus ID will be "CPUA".
Yes, this will change the directory names seen
in /proc/acpi/processor/* on some systems.
Before this patch, those directory names where
totally arbitrary strings based on the interal AML device strings.

ACPI: Add the reference count to avoid unloading ACPI video bus twice
Sometimes both acpi video and i915 driver are compiled as modules.
And there exists the strict dependency between the two drivers.
The acpi video bus will be unloaded in course of unloading the i915 driver.
If we unload the acpi video driver, then the kernel oops will be triggered.
Add the reference count to avoid unloading the ACPI video bus twice.
The reference count should be checked before unregistering the acpi video bus.
If the reference count is already zero, it won't unregister it again.
And after the acpi video bus is already unregistered, the reference count
will be set to zero.

ACPI: fix a deadlock in hotplug case
we used to run the hotplug code in keventd_wq.
But when hot removing the ACPI battery device,
power_supply_unregister invokes flush_scheduled_work.
This causes a deadlock. i.e
1. When dock is unplugged, all the hotplug code is run on kevent_wq.
2. the hotplug code removes all the child devices of dock device.
3. removing the child device may invoke flush_scheduled_work
4. flush_scheduled_work waits until all the work on kevent_wq to be
finished, while this will never be true because the hotplug code
is running on keventd_wq...
Introduce a new workqueue for hotplug in this patch.

ACPI: pci_root: check _CRS, then _BBN for downstream bus number
To find a host bridge's downstream bus number, we currently look at _BBN
first. If _BBN returns a bus number we've already seen, we conclude that
_BBN was wrong and look for a bus number in _CRS.
However, the spec[1] (figure 5-5 and the example in sec 9.12.1) and an ACPI
FAQ[2] suggest that the OS should use _CRS to discover the bus number
range, and that _BBN is really intended to bootstrap _CRS methods that
reference PCI opregions.
This patch makes us always look at _CRS first. If _CRS doesn't supply a
bus number, we look at _BBN. If _BBN doesn't exist, we default to zero.
This makes the behavior consistent regardless of device discovery order.
Previously, if A and B had duplicate _BBNs and we found A first, we'd only
look at B's _CRS, whereas if we found B first, we'd only look at A's _CRS.
I'm told that Windows discovers host bridge bus numbers using _CRS, so
it should be fairly safe to rely on this BIOS functionality.
This patch also removes two misleading messages: we printed the "Wrong _BBN
value, reboot and use option 'pci=noacpi'" message before looking at _CRS,
so we would likely find the bus number in _CRS, the system would work fine,
and the user would be confused. The "PCI _CRS %d overrides _BBN 0" message
incorrectly assumes _BBN was zero, and it's useless anyway because we

thinkpad-acpi: support the second fan on the X61
Support reading the tachometer of the auxiliary fan of a X60/X61.
It was found out by sheer luck, that bit 0 of EC register 0x31
(formely HBRV) selects which fan is active for tachometer readings
through EC 0x84/0x085: 0 for fan1, 1 for fan2.
Many thanks to Christoph Kl??nter, to Whoopie, and to weasel, who
helped confirm that behaviour.
Fan control through EC HFSP applies to both fans equally, regardless
of the state of bit 0 of EC 0x31. That matches the way the DSDT uses
HFSP.
In order to better support the secondary fan, export a second
tachometer over hwmon, and add defensive measures to make sure we are
reading the correct tachometer.
Support for the second fan is whitelist-based, as I have not found
anything obvious to look for in the DSDT to detect the presence of
the second fan.

thinkpad-acpi: forbid the use of HBRV on Lenovo ThinkPads
Forcing thinkpad-acpi to do EC-based brightness control (HBRV) on a
X61 has very... interesting effects, instead of doing nothing (since
it doesn't have EC-based backlight control), it causes "weirdness" in
the fan tachometer readings, for example.
This means the EC register that used to be HBRV has been reused by
Lenovo for something else, but they didn't remove it from the DSDT.
Make sure the documentation reflects this data, and forbid the user
from forcing the driver to access HBRV on Lenovo ThinkPads.

ACPI: use handle, not device, in system notification path
This patch changes the global system notification path so it uses the
acpi_handle, not the acpi_device.
System notifications often deal with device presence and status change.
In these cases, we may not have an acpi_device. For example, we may
get a Device Check notification on an object that previously was not
present. Since the object was not present, we would not have had an
acpi_device for it.

ACPI: allow drivers to request both device and system notify events
System notify events (0x00-0x7f) are common across all device types
and should be handled in Linux/ACPI, not in drivers. However, some
BIOSes use system notify events in device-specific ways that require
the driver to be involved.
This patch adds a ACPI_DRIVER_ALL_NOTIFY_EVENTS driver flag. When a
driver sets this flag and supplies a .notify method, Linux/ACPI calls
the .notify method for ALL notify events on the device, not just the
device-specific (0x80-0xff) events.

acpi_pci_bind/unbind are vastly simplified, and are only used

Looking up the ACPI-PCI binding is never in the performance path, and by

- eliminates struct acpi_device vs struct pci_dev lifetime issues
- lays more groundwork for eliminating .start from acpi_device_ops

- whacks out a lot of code

thinkpad-acpi: fix BEEP ACPI handler warnings
Some ThinkPads want two arguments for BEEP, while others want just
one, causing ACPICA to log warnings like this:
ACPI Warning (nseval-0177): Excess arguments - method [BEEP] needs 1,
found 2 [20080926]

thinkpad-acpi: store fw version with strict checking
Extend the thinkpad model and firmware identification data with the
release serial number for the BIOS and firmware (when available), as
that is easier to parse and compare than the version strings.
We're going to greatly extend the use of the ThinkPad DMI data through
quirk lists, so it is best to be quite strict and make sure what we
get from DMI is exactly what we expect, otherwise quirk matching may
result in quite insane things.
IBM (and Lenovo, at least for the ThinkPad line) uses this schema for
firmware versioning and model:
Firmware model: Two digits, [0-9A-Z]
Firmware version: AABBCCDD, where
AA = firmware model, see above
BB = "ET" for BIOS, "HT" for EC
CC = release version, two digits, [0-9A-Z],
"00" < "09" < "0A" < "10" < "A0" < "ZZ"
DD = "WW"

ACPI, PCI, x86: move MCFG parsing routine from ACPI to PCI file
Move
arch/x86/kernel/acpi/boot.c: acpi_parse_mcfg()
to
arch/x86/pci/mmconfig-shared.c: pci_parse_mcfg()
where it is used, and make it static.
Move associated globals and helper routine with it.
No functional change.
This code move is in preparation for SFI support,
which will allow the PCI code to find the MCFG table
on systems which do not support ACPI.

ACPI: don't check power state after _ON/_OFF
We used to evaluate _STA to check the power state of a device after
running _ON or _OFF. But as far as I can tell, there's no benefit
to evaluating _STA, and sometimes we trip over bugs when BIOSes don't
implement _STA correctly.
Yakui says Windows XP doesn't evaluate _STA during power transition.
So let's skip it in Linux, too. It's conceivable that we'll need to
check _STA in the future for some reason, but until we do, I don't
see a reason to clutter this code path.

PNPACPI: parse Extended Address Space Descriptors
Extended Address Space Descriptors are new in ACPI 3.0 and allow the
BIOS to communicate device resource cacheability attributes (write-back,
write-through, uncacheable, etc) to the OS.
Previously, PNPACPI ignored these descriptors, so if a BIOS used them,
a device could be responding at addresses the OS doesn't know about.
This patch adds support for these descriptors in _CRS and _PRS. We
don't attempt to encode them for _SRS (just like we don't attempt to
encode the existing 16-, 32-, and 64-bit Address Space Descriptors).
Unfortunately, I don't have a way to test this.

The ACPI0007 _HID used for processor "Device" objects in the namespace

ACPI: processor: check for synthetic _HID, default to "Device" declaration
This patch inverts the logic that distinguishes "Processor" statements
from "Device" statements, so we now check explicitly for "Processor" and
default to "Device". This removes the only real use of ACPI_PROCESSOR_HID,
so we can then remove the #define. It also has the theoretical advantage
that if a new processor _HID were ever added, we wouldn't have to change
the code here.

ACPI: use LNXCPU, not ACPI_CPU, for Linux-specific processor _HID
ACPI_PROCESSOR_OBJECT_HID is a synthetic _HID that Linux generates
for "Processor" definitions. Unlike "Device" definitions, "Processor"
definitions do not have a _HID in the namespace, so we generate a
fake _HID. By convention, all these fake _HIDs begin with "LNX".
This does change the user-visible _HID for "Processor" objects --
previously, we used "ACPI_CPU" and this changes that to "LNXCPU",
which starts with "LNX" as do all the other made-up _HIDs. This
change is visible in processor filenames and "hid" files under
/sys/devices/LNXSYSTM:00/.
