We need this information to test some bit so we know if TjMax is 100C or 85C. Intel claims this works for mobiles only, respect that and set for desktops the TjMax to 100C.

HWMON: coretemp, suspend fix It's not permitted to unregister a device after devices have been suspended. It causes deadlocks to appear on systems with coretemp hwmon loaded.  To avoid this, we can make coretemp_cpu_callback() do nothing if the _FROZEN bit is set in action.   Also, in other cases it's generally too late to unregister the coretemp device if the CPU is already dead, so it should be unregistered on CPU_DOWN_PREPARE.   Signed-off-by: Rafael J.
