Not this garbage again... sigh. Once again, I will want to know what
the actual constraint is... not just "oh, this seems to work on this one
system."
I realize that the kdump interfaces are probably beyond saving -- we
have had this discussion enough times -- but I'm not happy about it and
I will really want to know what the heck the real issue is.
Furthermore, such a function should NOT be private to x86 core; if it's
needed at all it should live in the memblock core.
