Yeah, okay, we should have some PHDRS statement here still.  You can drop
the dummy segment, and the notes segment as well, or you can keep the notes
section in both the notes and kernel segments.

Is the note segment useful at all ? I guess if we decide to keep it, we 
should have a reason.

I don't know if it is.

$ readelf -x17 powerpc64/kernel/vmlinux

Hex dump of section '.notes':

Does that look useful?  There's a build-id in there it seems.  I don't know
if any tools look at that, or how they find it.

(You patch doesn't apply btw, whitespace damage I think; will you send a
new one?)

Originally the patch is by Joel Stanley [off-list ref]

I guess he will send a v2 taking into account the discussion ?

Please do Joel :-)  Thanks in advance, etc.

Or maybe you can send it yourself as you are probably the best person to 
explain in details the change in the commit message.

I have no way of testing things properly.
