Ok this is a start. I'll have to review it again tomorrow and add more docs before I can do proper submit by email. If you're willing to contribute you can review it already using "git format-patch 9ca11f1" after fetching the repo. Comments welcome!
git clone --reference linux -b autonuma-dev-smt git://git.kernel.org/pub/scm/linux/kernel/git/andaa.git
The last patch in that branch is the last feature I worked on yesterday and it fixes the SMT load with numa02.c modified to use only 1 thread per core, which means changing THREADS from 24 to 12 in the numa02.c source at the top (and then building it again in the -DHARD_BIND and -DHARD_BIND -DINVERSE_BIND versions to compare with autonuma on and off). It also fixes building the kernel in a loop in KVM with 12 vcpus (now the load spreads over the two nodes). echo 0 >/sys/kernel/mm/autonuma/scheduler/smt would disable the SMT awareness.
