From: Zhang Rui rui.zhang@intel.com
[ Upstream commit 34cf8c657cf0365791cdc658ddbca9cc907726ce ]
Currently, coretemp driver supports only 128 cores per package. This loses some core temperature information on systems that have more than 128 cores per package. [ 58.685033] coretemp coretemp.0: Adding Core 128 failed [ 58.692009] coretemp coretemp.0: Adding Core 129 failed ...
Enlarge the limitation to 512 because there are platforms with more than 256 cores per package.
