WARNING: vmlinux.o(.text+0x340c): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init()
The function __boot_from_prom() references
the function __init prom_init().
This is often because __boot_from_prom lacks a __init 
annotation or the annotation of prom_init is wrong.

WARNING: vmlinux.o(.text+0x3628): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:early_setup()
The function start_here_multiplatform() references
the function __init early_setup().
This is often because start_here_multiplatform lacks a __init 
annotation or the annotation of early_setup is wrong.

WARNING: vmlinux.o(.text+0x3664): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references

This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
