Of note in this week's update are the merge of the new AMD 64bit
architecture, included in 2.5.5, and the merge of JFS in the latest 
2.5.6 prerelease.

Check the latest update at http://kernelnewbies.org/status/

A couple patches with with poetic names (futexes and radixes comes 
to mind) have been floating around recently.  Please let me know 
if you'd like me to add some of them to the list. 
Enjoy!
