Subject: [RFC PATCH V2 0/1] making order in file2alias

(this message is the RFC, the patch itself is expected to be fine)

This is a repost of what I've sent on Nov 4th.  Since Rusty asked to
only do the first step, here it is.  I rebased on next-20111201 and it
still works fine.

As for the previous 2/2 (see https://lkml.org/lkml/2011/11/4/127 ),
I still think it makes sense. And as Dave Martin suggested, we can
do without the array.

Thus, I may prepare three smaller steps, if that's acceptable (greg?)

  step 1: create the ELF section so ENTRY() lines can leave the array
          (and change name accordingly).

  step 2: each ENTRY() line can be moved just after the associated code
          (this means that a new bus is just a single hunk, not 2 of them)

  step 3: I create the headers needed to move code and ENTRY in separate
          files. This is some movement around, not trivial so it may
          deserve a patch in itself.

  step 4 and later ones: Individual busses may reach their own external file,
         conditionally compiled per Kconfig rules.

If that's something worth evaluating, I can do that over the weekend.

thanks
