[ 61/75] hwmon: (coretemp) Increase CPU core limit

From: Greg KH
Date: Fri May 04 2012 - 17:07:17 EST


3.3-stable review patch. If anyone has any objections, please let me know.

------------------

From: Guenter Roeck <guenter.roeck@xxxxxxxxxxxx>

commit bdc71c9a87b898e4c380c23b2e3e18071312ecde upstream.

CPU core ID is used to index the core_data[] array. The core ID is, however, not
sequential; 10-core CPUS can have a core ID as high as 25. Increase the limit to
32 to be able to deal with current CPUs.
