3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dan Carpenter <[email protected]> commit 5b3900cd409466c0070b234d941650685ad0c791 upstream. We fixed a bunch of integer overflows in timekeeping code during the 3.6 cycle. I did an audit based on that and found this potential overflow.
