Hello Goto-san,

Yes, as you surmise, I am mostly interested in the page migration
patches.  I was just trying to compile the hotplug patches to make
sure my "reordering" of the hotplug patchset (putting the page
migration patches first) didn't break hotplug.

I satisifed that goal by comparing the modified files after each
version of the hotplug patch (re-ordered versus original).  Since
the files turned out basically the same, that was good enough for
now.

I'm not sure why I couldn't get the hotplug patches to compile
on i386.  I used one of Dave Hansen's suggested configs.  Anyway
the comparison above was good enough for my purposes so I didn't
pursue this any further.

Of course, we also look forward to progress in the memory hotplug
area for ia64.
