    powerpc: Fix lwsync feature fixup vs. modules on 64-bit · 3d98ffbf
    Benjamin Herrenschmidt authored
    Anton's commit enabling the use of the lwsync fixup mechanism on 64-bit
    breaks modules. The lwsync fixup section uses .long instead of the
    FTR_ENTRY_OFFSET macro used by other fixups sections, and thus will
    generate 32-bit relocations that our module loader cannot resolve.
    
    This changes it to use the same type as other feature sections.
    
    Note however that we might want to consider using 32-bit for all the
    feature fixup offsets and add support for R_PPC_REL32 to module_64.c
    instead as that would reduce the size of the kernel image. I'll leave
    that as an exercise for the reader for now...
