* hwmon: (pc87427) Add temperature monitoring supportJean Delvare2010-08-14
| | | | | | | | | Add support for the 6 temperature monitoring channels of the PC87427. Note that the sensors resolution can vary, and I couldn't find a way to figure it out, so we might have to compensate in user-space.

* hwmon: (pc87427) Add support for the second logical deviceJean Delvare2010-08-14
| | | | | | | | | The second logical device contains the voltage and temperature registers. We have to extend the driver to support a second logical device before we can add support for these features.

* hwmon: (pc87427) Add support for manual fan speed controlJean Delvare2010-08-14
| | | | | | | | | | Add initial support for PWM outputs of the PC87427 Super-I/O chip. Only mode change and manual fan speed control are supported. Automatic mode configuration isn't supported, and won't be until at least one board is known, which makes uses of the PWM outputs.

* hwmon: (pc87427) Handle disabled fan inputs properlyJean Delvare2010-08-14
| | | | | | | | | Most fan input pins of the PC87427 can have alternate functions. Update the driver to check the configuration register and only support fan inputs which are really used for fan monitoring.

| | | | | | | | | | Fault files are for hardware failures that can be reported. So far we've seen chips reporting such failures for temperature sensors and fans, but not for voltages.

* hwmon: (ltc4245) Expose all GPIO pins as analog voltagesIra W. Snyder2010-08-14
| | | | | | | | | | | | | | | | | Add support for exposing all GPIO pins as analog voltages. Though this is not an ideal use of the chip, some hardware engineers may decide that the LTC4245 meets their design requirements when studying the datasheet. The GPIO pins are sampled in round-robin fashion, meaning that a slow reader will see stale data. A userspace application can detect this, because it will get -EAGAIN when reading from a sysfs file which contains stale data. Users can choose to use this feature on a per-chip basis by using either platform data or the OF device tree (where applicable). Signed-off-by: Ira W.

* hwmon: (pc87360) Fix device resource declarationJean Delvare2010-08-14
| | | | | | | | | | | | | | It's not OK to call platform_device_add_resources() multiple times in a row. Despite its name, this functions sets the resources, it doesn't add them. So we have to prepare an array with all the resources, and then call platform_device_add_resources() once. Before this fix, only the last I/O resource would be actually registered. The other I/O resources were leaked. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Jim Cromie <jim.cromie@gmail.com> Cc: stable@kernel.org

When invoking the crash kernel to write a dump, kdump_nmi_shootdown_cpus() uses NMI's to get all the cpu's to save their register context and halt. But the NMI interrupt handler runs a callback list. This patch sets a flag to prevent any of those callbacks from interfering with the halt of the cpu. For UV, which currently has the only callback to which this is relevant, the uv_handle_nmi() callback should not do dumping of stacks. The 'in_crash_kexec' flag is defined as an extern in kdebug.h firstly because x2apic_uv_x.c includes it. Secondly because some future callback might need the flag to know that it should not enter the debugger. (Such a scenario was in fact present in the 2.6.32 kernel, SuSE distribution, where a call to kdb needed to be avoided.)

It isn't just finding the source of the interrupt, but rather aids in decoding what the interrupt means.
