#     kbuild: change need-modorder implementation slightly
#     
#     Align with the need-builtin implementation.
#     
#     I also added need-modorder=1 to scripts/link-vmlinux.sh to make it more
#     future-proof; currently, we have no module in the init/ directory, but
#     if we had a one, scripts/Makefile.build would show a false positive
#     warning.

WARNING: vmlinux.o(.text+0x31fc): 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.

The function start_here_common() references
