[ Upstream commit 9c4e4c90ec24652921e31e9551fcaedc26eec86d ]
Otherwise, the following warning is encountered:
WARNING: vmlinux.o(.text+0x3dc6): 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.
