SRU justification:

Impact: i5 i7 cpus generate spurious softlock messages when coming
out of S3 because of a math overflow error in the softlock driver.

Fix: See attached patch that handles the overflow correctly, this is
backported from upstream.

Testcase: On i5 and i7 cpus suspend and then resume. Without the patch
there are several softlock messages with a timeout of 0 seconds. With
the patch the softlock messages do not occur.
