This patch fixes the following "Section mismatch" warnings when
build powerpc platforms.
-------------
WARNING: arch/powerpc/mm/built-in.o - Section mismatch: reference to
.init.text:early_get_page from .text between 'pte_alloc_one_kernel' (at offset
0xc68) and 'pte_alloc_one'
WARNING: mm/built-in.o - Section mismatch: reference to
.init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset
0x20300) and 'cache_reap'
-------------
Massive warnings represented by:
-------------
WARNING: arch/powerpc/kernel/built-in.o - Section mismatch: reference to
.init.data:.got2 from prom_entry (offset 0x0)
WARNING: arch/powerpc/platforms/built-in.o - Section mismatch: reference to
.init.text:mpc8313_rdb_probe from .machine.desc after 'mach_mpc8313_rdb' (at
offset 0x4)
