2013-06-13hwmon: (adm1021) Strengthen chip detection for ADM1021, LM84 and MAX1617Guenter Roeck
commit 591bfcfc334a003ba31c0deff03b22e73349939b upstream. On a system with both MAX1617 and JC42 sensors, JC42 sensors can be misdetected as LM84. Strengthen detection sufficiently enough to avoid this misdetection. Also improve detection for ADM1021. Modeled after chip detection code in sensors-detect command.

Commit 3e78080f8148 ('hwmon: (sht15) Check return value of regulator_enable()') depends on the use of devm_kmalloc() for automatic resource cleanup in the failure cases, which was introduced in 3.7. In older stable branches, explicit cleanup is needed.

2012-08-15x86: Simplify code by removing a !SMP #ifdefs from 'struct cpuinfo_x86'Kevin Winchester
commit 141168c36cdee3ff23d9c7700b0edc47cb65479f and commit 3f806e50981825fa56a7f1938f24c0680816be45 upstream. Several fields in struct cpuinfo_x86 were not defined for the !SMP case, likely to save space. However, those fields still have some meaning for UP, and keeping them allows some #ifdef removal from other files. The additional size of the UP kernel from this change is not significant enough to worry about keeping up the distinction: text data bss dec hex filename 4737168 506459 972040 6215667 5ed7f3 vmlinux.o.before 4737444 506459 972040 6215943 5ed907 vmlinux.o.after for a difference of 276 bytes for an example UP config. If someone wants those 276 bytes back badly then it should be implemented in a cleaner way.

commit 4ad33411308596f2f918603509729922a1ec4411 upstream. It makes sense to label "Digital Thermal Sensor" as "DTS", but unfortunately the string "dts" was already used for "Debug Store", and /proc/cpuinfo is a user space ABI. Therefore, rename this to "dtherm".

On high CPU load the accumulating values in the running_avg_cap register are very low (below 10), so averaging them too early leads to unnecessary poor output resolution.

commit 00250ec90963b7ef6678438888f3244985ecde14 upstream. Newer BKDG[1] versions recommend a different initialization value for the running average range register in the northbridge. This improves the power reading by avoiding counter saturations resulting in bogus values for anything below about 80% of TDP power consumption. Updated BIOSes will have this new value set up from the beginning, but meanwhile we correct this value ourselves. This needs to be done on all northbridges, even on those where the driver itself does not register at. This fixes the driver on all current machines to provide proper values for idle load.

commit c1c1a3d012fe5e82a9a025fb4b5a4f8ee67a53f6 upstream. By hwmon sysfs interface convention, setting pwm_enable to zero sets a fan to full speed.

In order to enable temperature mode aka automatic mode for the F75373 and F75375 chips, the two FANx_MODE bits in the fan configuration register need be set to 01, not 10.

commit 585c0fd8216e0c9f98e2434092af7ec0f999522d upstream. NCT6776F can select fan input pins for fans 3 to 5 with a secondary set of chip register bits. Check that second set of bits in addition to the first set to detect if fans 3..5 are monitored.

Without this fix, attempts to write temperature limits above the maximum supported by the chip (255 degrees Celsius) would arbitrarily and unexpectedly result in the limit being set to 0 degree Celsius.

Commit 2265cef2 (hwmon: (w83627ehf) Properly report PECI and AMD-SI sensor types) results in kernel panic if data->temp_label was not initialized. The problem was found with chip W83627DHG-P.

commit 2aba6cac2a84f3b80e11a680c34d55e7739b474d upstream. The definition of TO_ATTR_NO in the non-SMP case is wrong. As the SMP definition resolves to the correct value, just use this for both cases. Without this fix the temperature attributes are named temp0_* instead of temp2_*, so libsensors won't pick them. Broken since kernel 3.0.

commit 133d324d82e144588939ad25b732b5b6c33b03d9 upstream. Since 8-bit temperature values are now handled in 16-bit struct members, values have to be cast to s8 for negative temperatures to be properly handled.

2011-10-25hwmon: (w83627ehf) Properly report thermal diode sensorsJean Delvare
commit bf164c58e58328c40ebc597a8ac00cc6840f9703 upstream. The w83627ehf driver is improperly reporting thermal diode sensors as type 2, instead of 3. This caused "sensors" and possibly other monitoring tools to report these sensors as "transistor" instead of "thermal diode". Furthermore, diode subtype selection (CPU vs. external) is only supported by the original W83627EHF/EHG. All later models only support CPU diode type, and some (NCT6776F) don't even have the register in question so we should avoid reading from it.
