Oops, I didn't mean to take this discussion off the mailing list.
What about a combined approach ... architecture dependent code
should add all the interesting stuff to the vmlist, so kcore just
needs to walk the list to cover everything. We could also keep the
KCORE_BASE concept from my patch, but turn it into a variable that
the architecture dependent code can set to some suitable offset to
keep all the offsets in /proc/kcore positive. This will avoid
having to fixup binutils (at least until someone comes up with an
architecture where kernel space scatters across a wide enough range
that we can't keep the offsets positive).
