Kamezawa-San,

Thanks for the patchset. I would like to see these tested in -mm as well. The
complaint that I am hearing from Fedora is that for them to enable the memory
controller, they would like to see the struct page overhead go (for 32 bit
systems that have 32 byte cachelines). This series helps us address that issue
and helps with performance.
