hwmon: (coretemp) Fix oops on CPU offlining

2011-12-21T20:57:41+00:00

This is for stable kernel branch 3.0 only. Previous and later versions
have different code paths and are not affected by this bug.

This is the same fix as "hwmon: (coretemp) Fix oops on driver load"
but for the CPU offlining case. Sorry for missing it at first.

hwmon: (jz4740) fix signedness bug

2011-12-21T20:57:39+00:00

commit 0b57d7602b68f7b2786b2f0e22da39cbd4139a95 upstream.

wait_for_completion_interruptible_timeout() may return negative value.
In this case, checking if (t > 0)  will return true if t is unsigned.

hwmon: (coretemp) Fix oops on driver load

2011-12-09T16:52:34+00:00

This is for stable kernel branch 3.0 only. Previous and later versions
have different code paths and are not affected by this bug.

If the CPU microcode is too old, the coretemp driver won't work. But
instead of failing gracefully, it currently oops. Check for NULL
platform device data to avoid this.

hwmon: (w83627ehf) Fix broken driver init

2011-11-11T17:37:00+00:00

commit bfa02b0da66965caf46e441270af87edda4fea14 upstream.

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.

Add check if data->temp->label was set before use.

Based on incomplete patch by Alexander Beregalov.

hwmon: (w83627ehf) Properly report PECI and AMD-SI sensor types

2011-11-11T17:37:00+00:00

commit 2265cef2751b3441df91f85e0107f9f549e5b711 upstream.

When temperature sources are PECI or AMD-SI agents, it makes no sense
to report their type as diode or thermistor. Instead we must report
their digital nature.

hwmon: (coretemp) Fix for non-SMP builds

2011-11-11T17:36:59+00:00

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.

hwmon: (w83627ehf) Fix negative 8-bit temperature values

2011-10-25T05:10:17+00:00

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. This is broken since kernel version 2.6.39
(commit bce26c58df86599c9570cee83eac58bdaae760e4.)

hwmon: (w83627ehf) Properly report thermal diode sensors

2011-10-25T05:10:14+00:00

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.
