Module Name:    src
Committed By:   pooka
Date:           Wed Dec 12 11:10:56 UTC 2012

Modified Files:
        src/sys/kern: kern_rate.c

Log Message:
Signed overflow is undefined behavior, and one version of gcc
clearly tells us:

        kern_rate.c:98: warning: assuming signed overflow does not
        occur when assuming that (X + c) > X is always true

Check value against INT_MAX instead.  Also, for good measure throw
in a __predict() to flag the assumed common case.
