I guess what I want to understand is whether I (or someone) still
need(s) to sort out the vmlinux.lds issue.

If we're keeping inline spinlocks (I currently assume "yes"), then the
vmlinux.lds issue still needs fixing.  Is that correct?  However, if
we get rid of inline spinlocks we won't have the problem, though there
may be some performance impact -- hard to judge how significant.

Apologies if I'm being dense here...
