From: Greg Kroah-Hartman gregkh@linuxfoundation.org

commit 5132ede0fe8092b043dae09a7cc32b8ae7272baa upstream.

This reverts commit 6cfb521ac0d5b97470883ff9b7facae264b7ab12.

Turns out distros do not want to make retpoline as part of their "ABI", so this patch should not have been merged. Sorry Andi, this was my fault, I suggested it when your original patch was the "correct" way of doing this instead.
