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.
> WARNING: vmlinux(.text+0xc0101183): Section mismatch: reference to .init.text:start_kernel (between 'is386' and 'check_x87') 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.
