That's a beautifully presented patchset. Thanks for doing all that work - it helps.
UML maintenance appears to have ceased in recent times, so if we wish to have these changes runtime tested (we should) then I think it would be best if you could find someone to do that please.
And no akpm code-review would be complete without: dump_seek() is waaaay to large to be inlined. Is there some common .c file to where we could move it?
