I have tried hackbench but the number seem to be unstable on my system.
There may be various small optimizations still left to be done.
You cannot merge this without the patches up to the patch that implements
alien caches without performance issues. If you leave out the NUMA parts
then !NUMA is of course fine.
I would suggest to merge the cleanups first for the next upstream
merge cycle and give this patchset at least a whole -next cycle before
upstream merge.
