WARNING: vmlinux.o(.text+0x4630): 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+0x48c8): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
