Paul,
Sorry for breaking the build. I will be sure to CC you and
linuxppc-dev@ozlabs.org on future powerpc patches in this section name
cleanup project.
I think just reverting commits edada399 and 9203fc9c will cause a section
mismatch warning since commit 27b18332 removed the support code for the
.text.init.refok section. The following patch I believe should fix this
by effectively reverting just commit edada399. Can someone who has a
64-bit powerpc machine confirm?

powerpc: Revert switch to TEXT_TEXT in linker script
Commit edada399 broke the build on 64-bit powerpc because it moved the
__ftr_alt_* sections of a file away from the .text section, causing
link failures due to relative conditional branch targets being too far
away from the branch instructions. This happens on pretty much all
64-bit powerpc configs.
This change reverts commit edada399 while preserving the update from
the *.refok sections to .ref.text that has happened since.
