I think the main benefit is leaving some of the hard bits
wrt linking to the user-space linker.  Doesn't affect x86,
but it does affect at least alpha and ia64.

Well, due to the way shared libraries are constructed, the
.init sections *must* be loaded contiguously no matter what.
The question is, how to free that memory.

I believe it does.  This decision must be left to the per-arch
allocation routine though.
