I'm going to ask you (again...) to post future versions of this patchset to lkml. linux-mm is a limited forum and a lot of people who might be interested in percpu matters simply wont know about your patch-set. per-cpu is not just a VM matter, obviously - it affects architectures, core kernel code, etc. etc. I happened to see your patch-set and have a couple of comments about it but i will wait with discussing the issues until you submit these patches properly.
