Jeff Dike c83e448420 uml: an idle system should have zero load average
The ever-vigilant users of linode.com noticed that an idle 2.6 UML has a
persistent load average of ~.4.

It turns out that because the UML timer handler processed softirqs before
actually delivering the tick, the tick was counted in the context of the idle
thread about half the time.
