Read only one of the GPIO pins as an analog voltage. The ADC can be switched to a different GPIO pin at runtime, but this is not supported. Previously, this driver would report the analog voltage of the currently selected GPIO pin as all three GPIO voltages: in9_input, in10_input and in11_input. Signed-off-by:

Fixes from my driver review: http://lists.lm-sensors.org/pipermail/lm-sensors/2010-March/028051.html Only the small changes are in there, more important changes will come later separately as time permits. * Drop the remnants of the now gone detect function * The TMP102 has no known compatible chip * Include the right header files * Clarify why byte swapping of register values is needed * Strip resolution info bit from temperature register value * Set cache lifetime to 1/3 second * Don't arbitrarily reject limit values; clamp as needed * Make limit writing unconditional * Don't check for transaction types the driver doesn't use * Properly check for error when setting configuration * Report error on failed probe * Make the driver load automatically where needed * Various other minor fixes Signed-off-by:

Driver for the TI TMP102. The TI TMP102 is similar to the LM75. It differs from the LM75 by having a 16-bit conf register and the temp registers have a minimum resolution of 12 bits; the extended conf register can select 13-bit resolution (which this driver does) and also change the update rate (which this driver currently doesn't use).

The Apple SMC uses a systematic labeling scheme for the hardware temperature sensors. This scheme is currently hidden from userland. Since the sensor set, and consequently the numbering, differs between models, an extensive database of configurations is required for an application such as fan control. This patch adds the SMC labels to the hwmon sysfs interface, allowing applications to use the sensors more intelligibly. [rydberg@euromail.se: fixed error handling] Signed-off-by:

When the user passes the kernel parameter acpi_enforce_resources=lax, the ACPI resources are no longer protected, so a native driver can make use of them. In that case, we do not want the asus_atk0110 to be loaded. Unfortunately, this driver loads automatically due to its MODULE_DEVICE_TABLE, so the user ends up with two drivers loaded for the same device - this is bad. So I suggest that we prevent the asus_atk0110 driver from loading if acpi_enforce_resources=lax. Signed-off-by:

Commit e9fb7631 ("cpu-hotplug: introduce cpu_notify(), __cpu_notify(), cpu_notify_nofail()") also introduced this annoying warning: kernel/cpu.c:157: warning: 'cpu_notify_nofail' defined but not used when CONFIG_HOTPLUG_CPU wasn't set.

Kamezawa Hiroyuki requested documentation for the numa_mem_id() and slab related changes. He suggested Documentation/vm/numa for this documentation. Looking at this file, it seems to me to be hopelessly out of date relative to current Linux NUMA support. At the risk of going down a rathole, I have made an attempt to rewrite the doc at a slightly higher level [I think] and provide pointers to other in-tree documents and out-of-tree man pages that cover the details. Let the games begin. Signed-off-by:

In kernel profiling requires that we be able to allocate "local" memory for each cpu. Use "cpu_to_mem()" instead of "cpu_to_node()" to support memoryless nodes. Depends on the "numa_mem_id()" patch. Signed-off-by:
-
Lee Schermerhorn authored
Example usage of generic "numa_mem_id()": The mainline slab code, since ~ 2.6.19, does not handle memoryless nodes well. Specifically, the "fast path"--____cache_alloc()--will never succeed as slab doesn't cache offnode object on the per cpu queues, and for memoryless nodes, all memory will be "off node" relative to numa_node_id(). This adds significant overhead to all kmem cache allocations, incurring a significant regression relative to earlier kernels [from before slab.c was reorganized]. This patch uses the generic topology function "numa_mem_id()" to return the "effective local memory node" for the calling context. This is the first node in the local node's generic fallback zonelist-- the same node that "local" mempolicy-based allocations would use. This lets slab cache these "local" allocations and avoid fallback/refill on every allocation. N.B.: Slab will need to handle node and memory hotplug events that could change the value returned by numa_mem_id() for any given node if recent changes to address memory hotplug don't already address this. E.g., flush all per cpu slab queues before rebuilding the zonelists while the "machine" is held in the stopped state.
