This reverts commit e91abf80a0998f326107874c88d549f94839f13c.

Since

commit 24e4a8c3e8868874835b0f1ad6dd417341e99822
Author: John Stultz <john.stultz@linaro.org>
Date:   Wed Jul 16 21:03:53 2014 +0000

    ktime: Kill non-scalar ktime_t implementation for 2038

there is no longer a 32bit version that's unsigned, and we don't have
to jump through ridiculous hoops to make the calculations correct.

I didn't look whether there's more of this pattern in the kernel.
