Subject: [21/89] hwmon: (coretemp) Relax target temperature range check

2.6.39-stable review patch.  If anyone has any objections, please let us know.

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

From: Jean Delvare <khali@...ux-fr.org>

commit 4c6e0f8101e62d8b2d01dc94b835a98b191a1454 upstream.

The current temperature range check of MSR_IA32_TEMPERATURE_TARGET
seems too strict to me, some TjMax values documented in
Documentation/hwmon/coretemp wouldn't pass. Relax the check so that
all the documented values pass.
