Latest Git kernel: Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup()

Hi All,

I got the following error messages with the latest Git kernel today:

GEN     .version
   CHK     include/generated/compile.h
   LD      vmlinux.o
   MODPOST vmlinux.o
WARNING: vmlinux.o(.text+0x302a): 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.

   MODINFO modules.builtin.modinfo
   KSYM    .tmp_kallsyms1.o
   KSYM    .tmp_kallsyms2.o
   LD      vmlinux
   SORTEX  vmlinux
   SYSMAP  System.map
   CHKHEAD vmlinux

What does it mean?

Please find attached the kernel config.

Thanks,
Christian

Hi All,

I got the following error messages with the latest Git kernel today:

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.

The best first thing to do with these type of errors is to Google them. If
you see there are patches just assume somebody else is working on it. That
saves everybody time, because these things tend to get duplicate reports.

I proposed a patch for it at https://patchwork.ozlabs.org/patch/1097845/

Hello Christophe,

Could you please add this patch to the GIT kernel because the issue still exists.

Thanks,
Christian
