Because I must ask: if this feature is for one single computer which
presumably has a custom kernel, why add it to mainline Linux?

I think in particular patch 2 deserves to be merged because it removes
a ton of cruft from every call to put_page() (at least if you're using
a distro config).  It makes me nervous, but I think it's the right
thing to do.  It may well need more fixups after it has been merged,
but that's life.

Maybe we should split the first two patches into a separate series, and
get it merged first, while the more controversial stuff is still under
review?

Thanks,
