Linus,

Please revert commits edada399 ("powerpc: Use TEXT_TEXT macro in
linker script.") and 9203fc9c ("powerpc: Use __REF macro instead of
old .text.init.refok."), which depends on edada399.

Commit edada399 breaks the build because it moves 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.

Clearly these patches were never even build-tested.  They were never
acked by the powerpc maintainer (Ben) - because he was on vacation -
and they weren't sent to the deputy maintainer (me) or the relevant
mailing list (linuxppc-dev).

This is partly my fault :-(
I acked them as I did not see the issue with conditional branches.
Could I ask you to add a comment to the lds file about this.
