This is often because __boot_from_prom lacks a __init annotation or the annotation of prom_init is wrong. WARNING: vmlinux.o(.text+0x2fd0): 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.
