Subject: [PATCH V2 03/11] hwmon: (coretemp) Enlarge per package core count limit
Date: Fri,  2 Feb 2024 17:21:36 +0800

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.
