* hwmon: (coretemp) Fix compile error if CONFIG_SMP is not definedGuenter Roeck2011-05-23
| | | | | | | | | | | | | cpu_sibling_mask() is not defined unless CONFIG_SMP is defined, so it must not be used directly in the code without ifdef protection. To solve the problem and avoid ifdefs in the code, define for_each_sibling() and use it instead.

* hwmon: (coretemp) Merge pkgtemp with coretempDurgadoss R2011-05-20
| | | | | | | | | | | | | | This patch merges the pkgtemp with coretemp driver. The sysfs interfaces for all cores in the same pkg are shown under one directory, in hwmon. It also supports CONFIG_HOTPLUG_CPU. So, the sysfs interfaces are created when each core comes online and are removed when it goes offline.

| | | | | | | | | | | | | | | | | | | Make the LM75/LM75A device detection faster: * Don't read the current temperature value when we don't use it. * Check for unused bits in the configuration register as soon as we have read its value. * Don't use word reads, not all devices support this, and some which don't misbehave when you try. * Check for cycling register values every 40 register addresses instead of every 8, it's 5 times faster and just as efficient. Some of these improvements come straight from the user-space sensors-detect script, so both detection routines are in line now.
