I tested the patches, ran kernbench, lmbench and some tests with
parallel containers. Except for the one typo in the page migration
patch, the patches worked quite well. KAMEZAWA-San, could you please
send the updated patch with the compilation fix.

I am yet to test the migration fix (I am yet to get access to a NUMA/
box capable of fake NUMA). I have not measured the performance impact
of these patches.

Andrew, could you please consider these patches for -mm inclusion once
KAMEZAWA-San sends out the fixed migration patch.
