Here is the latest revision of the Simple Topology API discussed here on LKML 
last week.  The patch is against 2.5.28.  I have made changes to incorporate 
most of the feedback that I got from the last posting.  Some of the calls have 
changed from prctl() to syscalls.  A couple of functions have been optimized. 
Some files and config options have been renamed to be more in-sync with things 
I expect to happen in the near future.  And the locking was revised.

I look forward to additional discussion on both this and the Memory Binding API 
I'll be posting momentarily.

Cheers!
