Subject: mm section mismatch warnings for ps3

When building current mainline for ps3_defconfig, I get the following
mm-related section mismatches:

| WARNING: mm/built-in.o(.text+0x25094): Section mismatch in reference from the function .sparse_add_one_section() to the function .meminit.text:.sparse_index_init()
| The function .sparse_add_one_section() references
| the function __meminit .sparse_index_init().
| This is often because .sparse_add_one_section lacks a __meminit 
| annotation or the annotation of .sparse_index_init is wrong.
|
| WARNING: mm/built-in.o(.text+0x25128): Section mismatch in reference from the function .sparse_add_one_section() to the function .meminit.text:.sparse_init_one_section()
| The function .sparse_add_one_section() references
| the function __meminit .sparse_init_one_section().
| This is often because .sparse_add_one_section lacks a __meminit 
| annotation or the annotation of .sparse_init_one_section is wrong.
|
| WARNING: mm/built-in.o(.text+0x2c5fc): Section mismatch in reference from the function .__add_zone() to the function .meminit.text:.init_currently_empty_zone()
| The function .__add_zone() references
| the function __meminit .init_currently_empty_zone().
| This is often because .__add_zone lacks a __meminit 
| annotation or the annotation of .init_currently_empty_zone is wrong.
|
| WARNING: mm/built-in.o(.text+0x2c628): Section mismatch in reference from the function .__add_zone() to the function .meminit.text:.memmap_init_zone()
| The function .__add_zone() references
| the function __meminit .memmap_init_zone().
| This is often because .__add_zone lacks a __meminit 
| annotation or the annotation of .memmap_init_zone is wrong.
|
| WARNING: vmlinux.o(.text+0x7360): Section mismatch in reference from the function .start_secondary_prolog() to the function .devinit.text:.start_secondary()
| The function .start_secondary_prolog() references
| the function __devinit .start_secondary().
| This is often because .start_secondary_prolog lacks a __devinit 
| annotation or the annotation of .start_secondary is wrong.
|
| WARNING: vmlinux.o(.text+0x1dea0): Section mismatch in reference from the function .move_device_tree() to the function .init.text:.lmb_alloc_base()
| The function .move_device_tree() references
| the function __init .lmb_alloc_base().
| This is often because .move_device_tree lacks a __init 
| annotation or the annotation of .lmb_alloc_base is wrong.
|
| WARNING: vmlinux.o(.text+0xabd7c): Section mismatch in reference from the function .sparse_add_one_section() to the function .meminit.text:.sparse_index_init()
| The function .sparse_add_one_section() references

| This is often because .sparse_add_one_section lacks a __meminit 
| annotation or the annotation of .sparse_index_init is wrong.
|
| WARNING: vmlinux.o(.text+0xabe10): Section mismatch in reference from the function .sparse_add_one_section() to the function .meminit.text:.sparse_init_one_section()
| The function .sparse_add_one_section() references
| the function __meminit .sparse_init_one_section().
| This is often because .sparse_add_one_section lacks a __meminit 
| annotation or the annotation of .sparse_init_one_section is wrong.
|
| WARNING: vmlinux.o(.text+0xb3198): Section mismatch in reference from the function .add_memory() to the function .devinit.text:.arch_add_memory()
| The function .add_memory() references
| the function __devinit .arch_add_memory().
| This is often because .add_memory lacks a __devinit 
| annotation or the annotation of .arch_add_memory is wrong.
|
| WARNING: vmlinux.o(.text+0xb32e4): Section mismatch in reference from the function .__add_zone() to the function .meminit.text:.init_currently_empty_zone()
| The function .__add_zone() references
| the function __meminit .init_currently_empty_zone().
| This is often because .__add_zone lacks a __meminit 
| annotation or the annotation of .init_currently_empty_zone is wrong.
|
| WARNING: vmlinux.o(.text+0xb3310): Section mismatch in reference from the function .__add_zone() to the function .meminit.text:.memmap_init_zone()
| The function .__add_zone() references
| the function __meminit .memmap_init_zone().
| This is often because .__add_zone lacks a __meminit 
| annotation or the annotation of .memmap_init_zone is wrong.

(there are a few more regarding ps3_register_repository_device(), but these
 cannot happen as only storage devices can be added later)
