Ok, let me shout it out to you, hopefully you can understand me now:

THERE ARE NO FUNCTIONS BY THE NAME setup_read_mode OR set_real_mode IN
YOUR BRANCH OR ANYWHERE IN THE KERNEL!!!

$ git log -p yinghai/for-x86-boot-v7 | grep -EriIn '(setup_read_mode|set_real_mode)\W'
$ git log -p yinghai/for-x86-boot-v8 | grep -EriIn '(setup_read_mode|set_real_mode)\W'
$

Or do you mean that the function naming is wrong? WTF?
