Cannot apply sched-threading-2.4.21-E1 to 2.4.21 kernel

[Orion Poplawski]

I assumed that the scheduler patch sched-threading-2.4.21-E1 at 
http://people.redhat.com/mingo/O(1)-scheduler/ is designed to be applied 
to the 2.4.21 kernel?  I'm not having any luck:

....and so on.

Was this a mistaken assumption?
