I am finding a different commit ID:

commit baa25b571a168aff5a13bfdc973f1229e2b12b63
Author: Nicholas Piggin <npiggin at gmail.com>

    powerpc/64: Do not link crtsavres.o in vmlinux
     
    The 64-bit linker creates save/restore functions on demand with final
    links, so vmlinux does not require crtsavres.o.
