Building the ppc64 kernel with a modern binutils results in this warning: powerpc64le-linux-gnu-ld: warning: orphan section `.gnu.hash' from `linker stubs' being placed in section `.gnu.hash'
Alan Modra <amo...@gmail.com> explains: > .gnu.hash, like .hash, is used by glibc ld.so for dynamic symbol > lookup. I imagine you don't need either section in a kernel, so > discarding both sounds reasonable. Likely you could discard .interp > and .dynstr too, and .dynsym when !CONFIG_PPC32.
