Some of the above happens during the MODPOST where we check modules.
The recently added trick to use __init_refok should have 'killed' at least
the one referring to rest_init. But running the check on the final vmlinux have thrown
the .text.init.refok into .text.
Will try to work out a fix for it.

I too a quick look at this one yesterday.
Code in head.S (for i386) are usually .init.text but in CONFIG_HOTPLUG_CPU it us .text.
But start_kernel() is __init.
Is it correct assumed that start_kernel() is never called in the HOTPLUG case since we
are dealign with CPU #2 and more?
If this is true I will introduce the .text.init.refok section.
