For what it's worth: I can't reproduce this error with the cross
compiler now shipped with Fedora 20 (ie, powerpc64-linux-gnu-gcc (GCC)
4.8.1 20130717 (Red Hat 4.8.1-5)). It shows a nice and clean
AS arch/powerpc/mm/tlb_low_64e.o
in the output.
That's v3.15-rc6, with just this patch, and using a .config generated,
with "make oldconfig", from arch/powerpc/configs/ppc64e_defconfig.
