    [PATCH] Modules 3/3: Sort sections · 5b2f8076
    Rusty Russell authored
    RTH's final complaint (so far 8) was that we should sort the module
    sections: archs might require some sections to be adjacent, so they can
    all be reached by a relative pointer (ie.  GOT pointer).  This
    implements that reordering, and simplfies the module interface for
    architectures as well.
    
    Previously an arch could specify it wanted extra space, but not where
    that space would be.  The new method (used only by PPC so far) is to
    allocate an empty section (in asm/module.h or by setting LDFLAGS_MODULE
    to use an arch specific linker script), and expand that to the desired
    size in "module_frob_arch_sections()".
