2010-03-06dm mpath: pass struct pgpath to pg init doneMoger, Babu1-3/+2
This patch removes some unnecessary argument casting. There is no functional change with this patch. Passes 'struct pgpath' through to pg_init_done() instead of the enclosed 'struct dm_path'. Tested the changes with LSI storage..

2010-03-05hwmon: (tmp421) Restore missing inputsJean Delvare1-7/+7
An off-by-one error caused some inputs to not be created by the driver when they should. TMP421 gets only one input instead of two, TMP422 gets two instead of three, etc. Fix the bug by listing explicitly the number of inputs each device has.

2010-03-05hwmon: (g760a) Make rpm_from_cnt staticJean Delvare1-1/+1

2010-03-05hwmon: (it87) Validate auto pwm settingsJean Delvare2-0/+36
Before switching to automatic fan control mode, make sure that all the trip points make sense. Otherwise, the control loop could lead to weird fan behavior. Signed-off-by: Jean Delvare <[email protected]>
2010-03-05hwmon: (it87) Add support for old automatic fan speed controlJean Delvare2-4/+205
Add support for the automatic fan speed control interface as implemented by IT8705F chips up to revision F and IT8712F chips up to revision G. This implementation fits very well in our standard sysfs interface. I implemented the old and not the new interface because the only chip I have at hand is an old one, and the new interface is more difficult to map to the standard sysfs interface. Adding support later should be possible though, if someone with a supported chip is interested. Signed-off-by: Jean Delvare <[email protected]>
2010-03-05hwmon: (it87) Drop dead web links in documentationJean Delvare1-13/+5
Unfortunately ITE is no longer publicly providing datasheets for their IT87xxF series of chips. They may send them on request if you ask politely. Signed-off-by: Jean Delvare <[email protected]>
2010-03-05hwmon: (it87) Add an entry in MAINTAINERSJean Delvare1-0/+7

2010-03-05hwmon: (it87) Fix many checkpatch errors and warningsJean Delvare1-75/+87
Fix 20 errors and 11 warnings reported by the checkpatch script. The remainining errors would require more work. The remaining warnings will be addressed later. Signed-off-by: Jean Delvare <[email protected]>
2010-03-05hwmon: (it87) Add support for beep on alarmJean Delvare2-0/+126
The IT87xxF chips support beeping on alarm, if properly wired and configured. There is one control bit for each input type (temperature, fan, voltage.) Let the user see and change them. Signed-off-by: Jean Delvare <[email protected]>
2010-03-05hwmon: (it87) Create vid attributes by groupJean Delvare1-8/+7
Only VID-related attributes are left in it87_attributes_opt, so we might as well rename it to it87_attributes_vid and use this group to create all attributes at once. Signed-off-by: Jean Delvare <[email protected]>
2010-03-05hwmon: (it87) Refactor attributes creation and removalJean Delvare1-130/+103
There is a lot of code redundancy in the creation of the fan and pwm attributes. Move these attributes to arrays so that the code can be simplified. This in turns makes the attributes removal code larger, so move it to a separate function that can be called in both the standard removal case and the error path during probing. Signed-off-by: Jean Delvare <[email protected]>
2010-03-05hwmon: (it87) Expose the PWM/temperature mappingsJean Delvare1-4/+69
Let the user read the PWM-to-temperature mappings. Until the trip points are also exposed, this is essentially a way to know how the BIOS has set things up. The ability to change the settings will be added later, together with the trip points. Signed-off-by: Jean Delvare <[email protected]>
2010-03-05hwmon: (it87) Display fan outputs in automatic mode as suchJean Delvare1-38/+61
The it87 driver doesn't yet support automatic fan control. Let it at least tell the user when a fan output is in automatic mode. Also let the user switch from automatic mode (possibly set by the BIOS) to manual mode and back without losing the settings. Signed-off-by: Jean Delvare <[email protected]>
2010-03-05hwmon: (lm90) Add SMBus alert supportJean Delvare2-0/+75
Tested successfully with an ADM1032 chip on its evaluation board. It should work fine with all other chips as well. At this point this is more of a proof-of-concept, we don't do anything terribly useful on SMBus alert: we simply log the event. But this could later evolve into libsensors signaling so that user-space applications can take an appropriate action.

2010-03-05hwmon: (lm90) Restore configuration on exitJean Delvare1-4/+10
Restore the chip configuration when unloading the driver. This ensures we don't leave the chip running if it was initially stopped. Signed-off-by: Jean Delvare <[email protected]>

Now that we have correct COMMIT semantics in writeback_single_inode, we can reduce and simplify nfs_wb_all(). Also replace nfs_wb_nocommit() with a call to filemap_write_and_wait(), which doesn't need to hold the inode->i_mutex. With that done, we can eliminate nfs_write_mapping() altogether.
