Subject: [PATCH] powerpc/64: Fix section mismatch warnings.
Date: Thu, 26 Mar 2020 17:37:42 +0100 [thread overview]
Message-ID: <20200326163742.28990-1-msuchanek@suse.de> (raw)
Fixes the following warnings:
WARNING: vmlinux.o(.text+0x2d24): 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.
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.
