Closing due to no response; can't reproduce bugs without a proper testcase.

Is that the correct fix? No, that's certainly wrong. The caller of generate_canonical_option should never be passing an argument to an option that doesn't take one.

If not i'll upload my builddir, but it's large.

A simple test with a hello world works. On my kernel build when I strip the lto link command line down I get the error with gcc47 -fdump-cgraph-ipa -nostdlib -fuse-linker-plugin -flto=jobserver -fwhole-program -Wl,-m,elf_x86_64 -Wl,--build-id -o .tmp_vmlinux1 -Wl,-T,arch/x86/kernel/vmlinux.lds arch/x86/kernel/head_64.o arch/x86/kernel/head_64.o and not with (last file deleted) gcc47 -fdump-cgraph-ipa -nostdlib -fuse-linker-plugin -flto=jobserver -fwhole-program -Wl,-m,elf_x86_64 -Wl,--build-id -o .tmp_vmlinux1 -Wl,-T,arch/x86/kernel/vmlinux.lds arch/x86/kernel/head_64.o
