linux-next: build warnings after merge of the final tree (tip treee related)

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 2636 bytes --]

Hi all,

After merging the scsi-post-merge tree, today's linux-next build (powerpc
allnoconfig, i386 defconfig and others) produced these warnings (I build
with CONFIG_DEBUG_SECTION_MISMATCH=y):

WARNING: mm/built-in.o(.text+0x25910): Section mismatch in reference from the function memblock_find_in_range() to the function .init.text:memblock_find_base()
The function memblock_find_in_range() references
the function __init memblock_find_base().
This is often because memblock_find_in_range lacks a __init 
annotation or the annotation of memblock_find_base is wrong.

WARNING: mm/built-in.o(.text+0x25bfc): Section mismatch in reference from the function memblock_double_array() to the function .init.text:memblock_free()
The function memblock_double_array() references
the function __init memblock_free().
This is often because memblock_double_array lacks a __init 
annotation or the annotation of memblock_free is wrong.

WARNING: mm/built-in.o(.text+0x25c5c): Section mismatch in reference from the function memblock_double_array() to the function .init.text:memblock_find_base()
The function memblock_double_array() references
the function __init memblock_find_base().
This is often because memblock_double_array lacks a __init 
annotation or the annotation of memblock_find_base is wrong.

WARNING: mm/built-in.o(.text+0x26194): Section mismatch in reference from the function memblock_reserve_reserved_regions() to the function .init.text:memblock_reserve()
The function memblock_reserve_reserved_regions() references
the function __init memblock_reserve().
This is often because memblock_reserve_reserved_regions lacks a __init 
annotation or the annotation of memblock_reserve is wrong.

WARNING: mm/built-in.o(.text+0x2630c): Section mismatch in reference from the function memblock_free_reserved_regions() to the function .init.text:memblock_free()
The function memblock_free_reserved_regions() references
the function __init memblock_free().
This is often because memblock_free_reserved_regions lacks a __init 
annotation or the annotation of memblock_free is wrong.

WARNING: vmlinux.o(.text+0x10190): Section mismatch in reference from the function setup_initial_memory_limit() to the function .init.text:memblock_set_current_limit()
The function setup_initial_memory_limit() references
the function __init memblock_set_current_limit().
This is often because setup_initial_memory_limit lacks a __init 
annotation or the annotation of memblock_set_current_limit is wrong.

please check it, and it should get into core/memblock branch.

Your patch fixes some of the warnings, but still leaves these for a
powerpc allnoconfig build:

WARNING: mm/built-in.o(.text+0x25d80): Section mismatch in reference from the function memblock_double_array() to the function .init.text:memblock_free()
The function memblock_double_array() references
the function __init memblock_free().
This is often because memblock_double_array lacks a __init 
annotation or the annotation of memblock_free is wrong.

WARNING: mm/built-in.o(.text+0x26318): Section mismatch in reference from the function memblock_reserve_reserved_regions() to the function .init.text:memblock_reserve()
The function memblock_reserve_reserved_regions() references
the function __init memblock_reserve().
This is often because memblock_reserve_reserved_regions lacks a __init 
annotation or the annotation of memblock_reserve is wrong.

WARNING: mm/built-in.o(.text+0x26490): Section mismatch in reference from the function memblock_free_reserved_regions() to the function .init.text:memblock_free()
The function memblock_free_reserved_regions() references
the function __init memblock_free().
This is often because memblock_free_reserved_regions lacks a __init 
annotation or the annotation of memblock_free is wrong.

And these for a i386 defconfig build:

WARNING: mm/built-in.o(.text+0x1e261): Section mismatch in reference from the function memblock_is_memory() to the variable .init.data:memblock
The function memblock_is_memory() references
the variable __initdata memblock.
This is often because memblock_is_memory lacks a __initdata 
annotation or the annotation of memblock is wrong.

WARNING: mm/built-in.o(.text+0x1e27f): Section mismatch in reference from the function memblock_is_region_memory() to the variable .init.data:memblock
The function memblock_is_region_memory() references
the variable __initdata memblock.
This is often because memblock_is_region_memory lacks a __initdata 
annotation or the annotation of memblock is wrong.

v1 already changed them all to __init_memblock, so we should not have those warnings.

you must have old gcc, those functions are not used with i386.

They are still marked as __init in include/linux/memblock.h.  I don't
think that they need to be marked at all there.

I am not sure what the compiler version has to do with it, but I am using
gcc 4.4.4 which is fairly recent.  The X86 Kconfig selects HAVE_MEMBLOCK
unconditionally, so mm/memblock.c is built on i386.

Do not remove the "extern" key word.

It is normal C coding practice to mark declarations in header files with
extern.  It probably doesn't strictly matter for functions, but I have
seen a case where not doing so to a variable lead to multiple definitions
of the variable.  Consistency is also good.

This version fixes all the warnings for me.  So if you put the "extern"s

Yinghai, mind posting the final version of the patch as a standalone 
posting, with a proper changelog, and with the extern issue fixed as 
well, plus all Reported-by and Tested-by tags added?
