I removed the 3rd and 8th patches, left 1,2,4,5,6,7. and updated them in
above git tree.

I tested the kbuild, specjbb2005, aim9, fileio-cfq, hackbench and
dbench. on my NHM EP and 2 sockets SNB EP box. hackbench increased 3~5%
on both machines. kbuild has suspicious 2% increase. others has no clear
change.

Any more comments or concern about this patch?
