X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9f751b82b491d06c6438066b511d44fa4cc49168;p=linux-beck.git

powerpc/module: Add support for R_PPC64_REL32 relocations

We haven't seen these before, but the soon to be merged relative
exception tables support causes them to be generated.
