updated preemptive kernel for 2.4.21

I put an updated preempt-kernel patch up at:

http://www.kernel.org/pub/linux/kernel/people/rml/preempt-kernel/v2.4/

The patch is a rediff to 2.4.21, but also contains a number of fixes for preempt-unsafe code -- both longstanding issues and new problems arising from the 2.4.21 development cycle. Thanks to Joe Korty and various folks at MontaVista for a lot of the fixes.

Please give it a whirl. Or, even better, switch to 2.5

Enjoy,

Robert Love
