I suppose that this new member of zone descriptors, pageset, is a list
of page frames with order 1 in cache, or page assimility per cpu,
Order 0.
to increase performance, it's true ? cold is array of free pages per cpu
? and hot is used pages per cpu ?
Hot pages are pages where most of the data is probably still
in the CPU cache, while cold pages are pages where the data
probably isn't in the CPU cache any more.
