Ah, OK.  I assumed that extra room at the end was sufficient.

So I've taken your previous patch and renamed the function to
arch_mod_section_prepend().  If we decide not to kill those bad gcc versions,
I'll stick it in some other random file (lib/weak.c?  Blech...)

BTW, this is very late for this merge window.  I would have liked to see
this a month ago :(

Subject: module: fix module loading failure of large kernel modules for parisc

When creating the final layout of a kernel module in memory, allow the
module loader to reserve some additional memory in front of a given section.
This is currently only needed for the parisc port which needs to put the
stub entries there to fulfill the 17/22bit PCREL relocations with large
kernel modules like xfs.
