WARNING: vmlinux.o(.text+0x3128): 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+0x3164): 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.
