4d29196c53 at24: Use timeout also for read
Writes may take some time on EEPROMs, so for consecutive writes, we already
have a loop waiting for the EEPROM to become ready. Use such a loop for reads,
too, in case somebody wants to immediately read after a write. Detailed bug
report and test case can be found here:

6d4561110a sysctl: Drop & in front of every proc_handler.
For consistency drop & in front of every proc_handler.  Explicity

d39b7dd1dc sgi-gru: decrapfiy options_write() function
Not a single line of actual code in the function was really
fundamentally correct.

Problems ranged from lack of proper range checking, to removing the last
character written (which admittedly is usually '\n'), to not accepting
hex numbers even though the 'show' routine would show the data in that
format.

This tries to do better.

ab69a5ae2b iwmc3200top: Add Intel Wireless MultiCom 3200 top driver.
This patch adds Intel Wireless MultiCom 3200 top driver.
IWMC3200 is 4Wireless Com CHIP (GPS/BT/WiFi/WiMAX).
Top driver is responsible for device initialization and firmware download.
Firmware handled by top is responsible for top itself and
as well as bluetooth and GPS coms. (Wifi and WiMax provide their own firmware)
In addition top driver is used to retrieve firmware logs
and supports other debugging features

b835d7fbd5 max6875: Discard obsolete detect method
There is no point in implementing a detect callback for the MAX6875, as
this device can't be detected. It was there solely to handle "force"
module parameters to instantiate devices, but now we have a better sysfs
interface that can do the same.

So we can get rid of the ugly module parameters and the detect callback.
This basically divides the binary module size by 2.

f0d83679a8 eeprom/at25: bugfix "not ready" timeout after write
Under certain circumstances msleep(1) within the loop, which waits for the
EEPROM to be finished, might take longer than the timeout.  On the next
loop the status register might now return to be ready and therefore the
loop finishes.  The following check now tests if a timeout occurred and if
so returns an error although the device reported it was ready.

This fix replaces testing the occurrence of the timeout by testing the
"not ready" bit in the status register.

405f55712d headers: smp_lock.h redux
* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

"allocate from the current node".  However, a number of the callers in

with VM_BUG_ON().  Callers that know their node is valid are then
converted.

For an upcoming distro release, we need to have the xp kernel module
loadable even when not on UV equipment.  The xpc module will not load.
This will allow one set of modules dependent upon xp to work on either UV
or non-UV equipment.

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.

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.

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.

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.

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.
