powerpc: Fix lwsync feature fixup vs. modules on 64-bit
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... Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
