Section mismatch in reference from the function .early_init_mmu() to the function .init.text:.radix__early_init_mmu() after PowerPC updates 5.7-1

[Christian Zigotzky <chzigotzky@xenosoft.de>]

Hello,

Since the PowerPC updates 5.7-1 we have the following issue during the 
linking of vmlinux:

MODPOST vmlinux.o
WARNING: modpost: vmlinux.o(.text.unlikely+0x1a0): Section mismatch in 
reference from the function .early_init_mmu() to the function 
.init.text:.radix__early_init_mmu()
The function .early_init_mmu() references
the function __init .radix__early_init_mmu().
This is often because .early_init_mmu lacks a __init
annotation or the annotation of .radix__early_init_mmu is wrong.

WARNING: modpost: vmlinux.o(.text.unlikely+0x1ac): Section mismatch in 
reference from the function .early_init_mmu() to the function 
.init.text:.hash__early_init_mmu()
The function .early_init_mmu() references
the function __init .hash__early_init_mmu().
This is often because .early_init_mmu lacks a __init
annotation or the annotation of .hash__early_init_mmu is wrong.

But the kernel works without any problems after the linking.

I reverted the following commits:

70fbdfef4ba63eeef83b2c94eac9a5a9f913e442 -- sysfs: remove redundant 
__compat_only_sysfs_link_entry_to_kobj fn

d38c07afc356ddebaa3ed8ecb3f553340e05c969 -- Merge tag 'powerpc-5.7-1' of 
git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

And after that the linking of vmlinux works again.

Please check the PowerPC updates 5.7-1.

Thanks,
Christian
