Jack Steiner a24e5e1caf sgi-gru: change GRU CCH commands from inline functions to outofline functions
Change the GRU instructions that manage contexts from inline functions to
out-of-line functions.  This simplifies adding statistics & error checking
to these functions.

Jack Steiner fe5bb6b00c sgi-gru: misc GRU cleanup
Misc trivial GRU drivers fixes:
	- fix long lines
	- eliminate extra whitespace
	- eliminate compiler warning
	- better validation of invalidate user parameters
	- bug fix for GRU TLB flush (not the cpu TLB flush)

These changes are all internal to the SGI GRU driver and have no effect
on the base kernel.

David Brownell 14dd1ff0f9 memory_accessor: implement the new memory_accessor interfaces for SPI EEPROMs
- Define new setup() hook to export the accessor
 - Implement accessor methods

Moves some error checking out of the sysfs interface code into the layer
below it, which is now shared by both sysfs and memory access code.

Kevin Hilman 7274ec8bd7 memory_accessor: implement the new memory_accessor interface for I2C EEPROM
In the case of at24, the platform code registers a 'setup' callback with
the at24_platform_data.  When the at24 driver detects an EEPROM, it fills
out the read and write functions of the memory_accessor and calls the
setup callback passing the memory_accessor struct.  The platform code can
then use the read/write functions in the memory_accessor struct for
reading and writing the EEPROM.

Add a driver for Intersil's ISL29003 ambient light sensor device plus some
documentation.  Inspired by tsl2550.c, a driver for a similar device.

It is put in drivers/misc for now until the industrial I/O framework gets

David Altobelli 891f7d73ea hpilo: reduce frequency of IO operations
Change hpilo open and close logic to spin for 10usec between checking device,
rather than every usec.

Because the loop is coded to take up to 10ms, it seemed prudent to
increase the interval between polling the device, to reduce the load on
the system and allow more other work to happen.

A missing type cast results in writing way beyond the end of a kzalloc()'d

David Altobelli c073b2db00 hpilo: open/close fix
The device can take a while to respond to an open/close request, so
increase the time kernel will wait for response (1 ms to 10ms).

Also, properly clean up a channel on a failed open, by calling the channel
close routine.  Just freeing the memory isn't sufficient, the device needs
to be informed that the channel is no longer open, and the device memory
cleared of references to freed dma buffer.

Dean Nelson 158bc69eff sgi-xp: eliminate false detection of no heartbeat
After XPC has been up and running on multiple partitions for any length of
time, if XPC on one of the partitions is stopped and restarted (either by
a rmmod/insmod or a system restart), it is possible for the XPCs running
on the other partitions to falsely detect a lack of heartbeat from the XPC
that was just restarted.  This false detection will occur if the restarted
XPC comes up within the five-seconds preceding one of the other XPC's
heartbeat check (which occurs once every twenty seconds).

The detection of no heartbeat results in the detecting XPC deactivating
from the just restarted XPC.  The only remedy is to restart one of the
XPCs and hope that one doesn't hit this five-second window on any of the
other partitions.

Tony Vroon f87a1a5f6c fujitsu-laptop: Simplify SBLL/SBL2 backlight handling
GBLS and GBLL only differ in the clearing of the GHKS flag, so there is no need
to have two backlight level readouts. Also, per Peter Gruber, the need for the
BLNF check has disappeared.
As a result, cleanups can be made in the code. This has been tested on the both
the S6410 and the S6420 platforms and causes no functionality regressions, on
the console without X or within X. One module parameter to disable the hotkeys
is dropped, as we only ever took one codepath anyway.

Tony Vroon 3a40708609 fujitsu-laptop: Add BL power, LED control and radio state information
The FUNC interface in the Fujitsu-Siemens DSDT was unused until now. It exposes
state information that is now reported in additional platform files (whether the
radios are killed by the hardware switch or operational, whether the machine is
docked and whether the lid is open).
Support for the backlight class is now extended with the ability to power the
backlight on & off. Optional support for the LED class allows the keyboard
headlamps found on the U810 netbook and the Fujitsu logo illumination on the
P8010 notebook to be turned on & off.

This was fed through checkpatch.pl and tested on the S6420, P8010 & U810 platforms.

This driver makes use of the dcdbas interface to the Dell firmware to
allow the backlight and rfkill interfaces on Dell systems to be driven
through the standardised sysfs interfaces.

Brent Casavant 08adefd479 ioc4: automatically load sgiioc4 subordinate module
Modify ioc4 to always load the sgiioc4 IDE module if the board carrying
the IOC4 hardware actually implements the IDE interface (not all boards
bring this functionality off the IOC4 chip).  A drive hosted on the IDE
interface may contain the root filesystem, and sgiioc4 doesn't load
automatically as ioc4 owns the PCI device ID, not sgiioc4.

Move x86 platform specific drivers from drivers/misc/
to a new home under drivers/platform/x86/.

The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually
implement the ACPI specification, but either simply
use ACPI, or implement vendor-specific ACPI extensions.

In the future we anticipate...
drivers/misc/ will go away.
other architectures will create drivers/platform/<arch>

Henrique de Moraes Holschuh 0081b16202 ACPI: thinkpad-acpi: fix fan sleep/resume path
This fixes a regression from v2.6.27, caused by commit
5814f737e1cd2cfa2893badd62189acae3e1e1fd, "ACPI: thinkpad-acpi:
attempt to preserve fan state on resume".

It is possible for fan_suspend() to fail to properly initialize
fan_control_desired_level as required by fan_resume(), resulting on
the fan always being set to level 7 on resume if the user didn't
touch the fan controller.

In order to get fan sleep/resume handling to work right:

1. Fix the fan_suspend handling of the T43 firmware quirk. If it is
still undefined, we didn't touch the fan yet and that means we have no
business doing it on resume.

2. Store the fan level on its own variable to avoid any possible
issues with hijacking fan_control_desired_level (which isn't supposed
to have anything other than 0-7 in it, anyway).

3. Change the fan_resume code to me more straightforward to understand
(although we DO optimize the boolean logic there, otherwise it looks
disgusting).

4. Add comments to help understand what the code is supposed to be
doing.

5. Change fan_set_level to be less strict about how auto and
full-speed modes are requested.

After commit 540b8bb9c33935183ceb5bed466a42ad72b2af56:

  sony-laptop: fingers off backlight if video.ko is serving this functionality

I can't set brightness on my sony laptop (nothing in /sys/class/backlight).
dmesg says "sony-laptop: Sony: Brightness ignored, must be controlled by ACPI
video driver".

The function acpi_video_backlight_support returns 0 if we should use the
vendor-specific backlight support, while non-0 if the ACPI generic should
be used. Because of this, the check introduced by the said commit appears
reversed.

WARNING: drivers/misc/fujitsu-laptop.o(.text+0xbde): Section mismatch in reference from the function acpi_fujitsu_add() to the variable .init.data:fujitsu_dmi_table
The function acpi_fujitsu_add() references
the variable __initdata fujitsu_dmi_table.
This is often because acpi_fujitsu_add lacks a __initdata
annotation or the annotation of fujitsu_dmi_table is wrong.

Bjorn Helgaas 8950d89aca ACPI: remove CONFIG_ACPI_EC
Remove CONFIG_ACPI_EC.  It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".

Per section 6.5.4 of the ACPI 3.0b specification,

    OSPM must make Embedded Controller operation regions, accessed
    via the Embedded Controllers described in ECDT, available before
    executing any control method.

The ECDT table is optional, but if it is present, the above text
means that the EC it describes is a required part of the ACPI
subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.

Al Viro 233e70f422 saner FASYNC handling on file close
As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.

So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set.  And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.

For the time being build for ia64-sn2 alone when CONFIG_IA64_GENERIC is

This eliminates a dependency of the XP/XPC drivers on having the GRU

system.

On such a system the GRU driver serves no useful purpose.

Henrique de Moraes Holschuh 75700e53cd ACPI: thinkpad-acpi: attempt to preserve fan state on resume
Attempt to preserve fan state across sleep and hibernation if the fan
control mode is enabled.

For safety reasons, only the PWM OFF (fan at 100%) or maximum
closed-loop level (level 7) are preserved.  If the fan state was set
to anything else, it will not be restored.

Also, should the fan be at PWM OFF mode at resume, it will be left at
that state (but this is extremely unlikely, no ThinkPad firmware was
ever reported to do this).

For reference, the known states used for fan control upon resume by
the firmware  are either "auto" or "level 7" depending on whether the
laptop wakes due to normal conditions or a thermal emergency.

The AE_BAD_ADDRESS exception code is now unused in ACPICA.
For linux, it's only used at wmi.c and acer-wmi.c.
I checked both wmi.c and acer-wmi.c, the AE_BAD_ADDRESS exception code
has no special meaning. The parent functions just call AE_SUCCESS() or
AE_FAILURE() to check the return status.
So it's safe to replace AE_BAD_ADDRESS with AE_ERROR.

This patch (mostly from Peter Gruber) improves the handling of the hotkeys
for P8010 laptops by passing more accurate input events back to userspace.
This is needed because the P8010 labels these buttons quite differently to
earlier laptops.  As part of this, a P8010-specific DMI callback check has
been implemented.  Finally there's some minor whitespace cleanups from
running the source through Lindent.

Carlos Corbacho 0606e1abfc acer-wmi: Add rfkill support for wireless and bluetooth
This patch implements rfkill support for the wireless and bluetooth devices
commonly found on Acer laptops.

For now, we will always poll these devices once a second to guarantee we
can catch state changes. On newer Acer laptops, it may be possible to rely
on WMI events to do this instead, and experimental support for this will be
added in a later patch.

3G has been deliberately left off for now, as we still have no way to
detect it, (nor, AFAIK, has any Linux user tried the code) and on laptops
that don't support 3G, trying to poll for the status will leave the logs
full of ACPI tracebacks.

The old sysfs interface for wireless and bluetooth will be removed in a
later patch.

(Thanks to Henrique de Moraes Holschuh and Dmitry Torokhov for reviewing
this patch).

Harald Welte 709ee531c1 panasonic-laptop: add Panasonic Let's Note laptop extras driver v0.94
This is a driver for ACPI extras such as hotkeys and backlight
brightness control on various Panasonic "Let's Note" series laptop
computers.

It exports the backlight via the backlight class device API,
and the hotkeys as input event device.  Some more esoteric
items like number of installed batteries are exported via sysfs
device attributes.

Hotkey events also generate old-style ACPI enents through
/proc/acpi/event to interoperate with current versions of acpid.

Robin Holt 8275d102f8 ia64: fix panic during `modprobe -r xpc'
If you are on ia64 and you modprobe xpc then modprobe -r xpc, you
immediately get a panic.  xpc depends on xp which depends on gru for a
symbol.  That symbol is only used when we are running on UV hardware.

Currently, the GRU driver detects we are not on UV hardware and does no
initializing.  It does not do the same check when unloading.  As a result,
the gru driver attempts to tear down stuff that was not setup.

This is a simple two-line workaround to get us through this release.  Once
2.6.28 is opened, we need to rework the symbols that xp is depending on
from gru so the gru driver can properly fail to load when hardware is not
available.

Jonathan Woithe d8196a93b1 fujitsu-laptop: fix regression for P8010 in 2.6.27-rc
The following patch (based on a patch from Stephen Gildea) fixes a
regression with the LCD brightness keys on Fujitsu P8010 laptops which was
observed with the 2.6.27-rc series (basically they stopped working due to
changes within the fujitsu-laptop and video modules).  Please apply to
2.6.27-rc and acpi git.

A more complete solution for this laptop will be included in an upcoming
patch, hopefully for 2.6.28.  In the meantime this restores most
functionality for P8010 users.

Matthew Garrett 3f6e2f137c hp-wmi: update to match current rfkill semantics
hp-wmi currently changes the RFKill state by altering the struct members
rather than using the dedicated interface, meaning that update events
won't be pushed to userspace.  This patch fixes that, along with fixing
the declared type of the WWAN kill switch.  It also ensures that rfkill
interfaces are only registered for hardware that exists.

Arjan van de Ven 83097aca85 Fix oops in acer_wmi driver (acer_wmi_init)
The acer_wmi driver does a DMI scan for quirks, and then sets flags into the
"interface" datastructure for some cases. However, the quirks happen real early
before "interface" is per se initialized from NULL.

The patch below 1) adds a NULL pointer check and 2) (re)runs the quirks at the
end, when "interface" has it's final value.

Carlos Corbacho 5c742b45dd acer-wmi: Fix wireless and bluetooth on early AMW0 v2 laptops
In the old acer_acpi, I discovered that on some of the newer AMW0 laptops
that supported the WMID methods, they don't work properly for setting the
wireless and bluetooth values.

So for the AMW0 V2 laptops, we want to use both the 'old' AMW0 and the
'new' WMID methods for setting wireless & bluetooth to guarantee we always
enable it.

This was fixed in acer_acpi some time ago, but I forgot to port the patch
over to acer-wmi when it was merged.

(Without this patch, early AMW0 V2 laptops such as the Aspire 5040 won't
work with acer-wmi, where-as they did with the old acer_acpi).

Jack Steiner 34d8a380d7 GRU Driver: hardware data structures
This series of patches adds a driver for the SGI UV GRU.  The driver is
still in development but it currently compiles for both x86_64 & IA64.
All simple regression tests pass on IA64.  Although features remain to be
added, I'd like to start the process of getting the driver into the
kernel.  Additional kernel drivers will depend on services provide by the
GRU driver.

The GRU is a hardware resource located in the system chipset.  The GRU
contains memory that is mmaped into the user address space.  This memory
is used to communicate with the GRU to perform functions such as
load/store, scatter/gather, bcopy, AMOs, etc.  The GRU is directly
accessed by user instructions using user virtual addresses.  GRU
instructions (ex., bcopy) use user virtual addresses for operands.

The GRU contains a large TLB that is functionally very similar to
processor TLBs.  Because the external contains a TLB with user virtual
address, it requires callouts from the core VM system when certain types
of changes are made to the process page tables.  There are several MMUOPS
patches currently being discussed but none has been accepted into the
kernel.  The GRU driver is built using version V18 from Andrea Arcangeli.

This patch:

Contains the definitions of the hardware GRU data structures that are used
by the driver to manage the GRU.

Henrique de Moraes Holschuh 0e74dc2646 ACPI: thinkpad-acpi: add bluetooth and WWAN rfkill support
Add a read/write rfkill interface to the bluetooth radio switch on the
bluetooth submodule, and one for the wireless wan radio switch to the wan
submodule.

Since rfkill does care for when a switch changes state, use WLSW
notifications to also check if the WWAN or Bluetooth switches did not
change state (due to them being slaves of WLSW in firmware/hardware, but
that reality not being always properly exported by the thinkpad firmware).

Henrique de Moraes Holschuh 133ec3bd3a ACPI: thinkpad-acpi: WLSW overrides other rfkill switches
On ThinkPads where the WLSW switch exists, the firmware or the hardware
ANDs the WLSW state with the device-specific switches (WWAN, Bluetooth).
It is downright impossible to enable WWAN or Bluetooth when WLSW is
blocking the radios.

This reality does not necessarily carry over to the WWAN and Bluetooth
firmware interfaces, though... so the state thinkpad-acpi was reporting
could be incorrect.

Tie the three switches in the driver so that we keep their state sane.
When WLSL is off, force the other switches to off as well.

Add a debugfs file for showing the full results of the method we use to

This should be useful in the case that a Linux user gets an Acer laptop

so we can get some feedback on how this value changes in these cases.

(At the moment, we always enable the wireless and 3G control. In the case
of the former, this is fairly safe. In the case of the latter though,
trying to toggle this device if it doesn't exist on a laptop causes ACPI
warnings/ errors).

To summarise: If you have an Acer laptop with a built in 3G card, please
report back the value from this file.

Carlos Corbacho 9991d9f2bc acer-wmi: Blacklist backlight on Acer Aspire 1520 & 1360 series
A newer BIOS for these laptops adds ACPI-WMI support to them. However, it does
not add support for the backlight via the EC, and we have no way to detect
this on older machines, so blacklist it from them.

Jonathan Woithe 20b937343e Fujitsu-laptop update
Add additional capabilities to the Fujitsu-laptop driver.

 * Brightness hotkey actions are sent to userspace. This can be disabled
   using a module parameter if it causes issues with models which handle
   these keys transparently in the BIOS.

 * Actions of additional hotkeys found on some Fujitsu models (eg: the
   suspend key and the dedicated "power on passphrase" keys) are broadcast
   to userspace.

 * An alternative brightness control method used by some Fujitsu models
   (for example, the S6410) is now supported, enabling software brightness
   controls on models using this method.

 * DMI-based module aliases are configured for the S6410 and S7020.

 * The current LCD brightness after booting should now be reflected in the
   standard backlight interface sysfs file (previously it was always set to
   0).  The platform brightness sysfs interface has always been fine.

Thanks go to Peter Gruber who provided a significant portion of this code
and tested various iterations of the patch on his S6410.

Cezary Jackiewicz 5411552c70 misc,acpi,backlight: compal Laptop Extras
This is driver for Compal Laptop: FL90/IFL90, based on MSI driver.

This driver exports a few files in /sys/devices/platform/compal-laptop/:
 lcd_level - screen brightness: contains a single integer in the range 0..7 (rw)
 wlan - wlan subsystem state: contains 0 or 1 (rw)
 bluetooth - bluetooth subsystem state: contains 0 or 1 (rw)
 raw - raw value taken from embedded controller register (ro)

In addition to these platform device attributes the driver registers itself
in the Linux backlight control subsystem and is available to userspace under
/sys/class/backlight/compal-laptop/.

Henrique de Moraes Holschuh 24e45bbe69 thinkpad-acpi: fix LED handling on older ThinkPads
The less tested codepaths for LED handling, used on ThinkPads 570, 600e/x,
770e, 770x, A21e, A2xm/p, T20-22, X20 and maybe a few others, would write
data to kernel memory it had no business touching, for leds number 3 and
above.  If one is lucky, that illegal write would cause an OOPS, but
chances are it would silently corrupt a byte.

The problem was introduced in commit af116101, "ACPI: thinkpad-acpi: add
sysfs led class support to thinkpad leds (v3.2)".

Fix the bug by refactoring the entire code to be far more obvious on what
it wants to do.  Also do some defensive "constification".

Issue reported by Karol Lewandowski <lmctlx@gmail.com> (he's an lucky guy
and got an OOPS instead of silent corruption :-) ).

Root cause of the OOPS identified by Adrian Bunk <bunk@kernel.org>.
Thanks, Adrian!

Henrique de Moraes Holschuh 9c0a76e16e thinkpad-acpi: fix initialization error paths
Rework some subdriver init and exit handlers, in order to fix some
initialization error paths that were missing, or broken.

Hitting those bugs should be extremely rare in the real world, but should
that happen, thinkpad-acpi would fail to dealocate some resources and a
reboot might well be needed to be able to load the driver again.

Jason Wessel b33cb815b5 kgdbts: Use HW breakpoints with CONFIG_DEBUG_RODATA
Whenever CONFIG_DEBUG_RODATA is set in the kernel config many kernel
text sections become read-only, and the use of software breakpoints in
the kgdb tests will cause the kernel to fail to complete the start up.

Until such time that there is an official API for modifying read-only
text sections hardware breakpoints must be used to run the do_fork or
sys_open tests or the tests get skipped.

Also fix the duplicated include reported by:
