[-stable PATCH] UML - fix uptime

[Jeff Dike]

Please consider this for 2.6.17-stable.  It made -mm briefly, but missed
2.6.17.  It fixes the value of uptime, which was broken by a patch late in
2.6.17-rc.

The use of unsigned instead of unsigned here broke the calculations on
negative numbers that are involved in calculating wall_to_monotonic.
