If krealloc() returns NULL, it doesn't free the original. So any code
of the form 'foo = krealloc(foo, ...);' is almost certainly a bug.

On systems with no package MSR support this caused crash as there
is a bug in the logic to check presence of DTHERM and PTS feature
together. Added a change so that when there is no PTS support, module
doesn't get loaded. Even if some CPU comes online with the PTS
feature disabled, and other CPUs has this support, this patch
will still prevent such MSR accesses.

This driver register CPU digital temperature sensor as a thermal
zone at package level.
Each package will show up as one zone with at max two trip points.
These trip points can be both read and updated. Once a non zero
value is set in the trip point, if the package package temperature
goes above or below this setting, a thermal notification is
generated.
