This patch gives me: arch/powerpc/kernel/module_64.c: In function 'dedotify_versions': arch/powerpc/kernel/module_64.c:325:33: error: 'reloc_start' undeclared (first use in this function) arch/powerpc/kernel/module_64.c:325:33: note: each undeclared identifier is reported only once for each function it appears in Cheers, Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
