This patch was dropped because it is obsolete
------------------------------------------------------
Subject: revert jdelvare-hwmon-hwmon-coretemp-new-driver
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
ERROR: "rdmsr_safe_on_cpu" [drivers/hwmon/coretemp.ko] undefined!
The rdmsr situation is bad, and will remain bad until the x86_64 tree gets
fixed.
Revert this patch locally from -mm.
