Subject: [PATCH] [PATCH] powerpc: remove duplicate EXPORT_SYMBOLS

remove warnings when building a 64bit kernel.
smp_call_function triggers also with 32bit kernel.

WARNING: vmlinux: duplicate symbol 'smp_call_function' previous definition was in vmlinux
arch/powerpc/kernel/ppc_ksyms.c:164:EXPORT_SYMBOL(smp_call_function);
arch/powerpc/kernel/smp.c:300:EXPORT_SYMBOL(smp_call_function);

WARNING: vmlinux: duplicate symbol 'ioremap' previous definition was in vmlinux
arch/powerpc/kernel/ppc_ksyms.c:113:EXPORT_SYMBOL(ioremap);
arch/powerpc/mm/pgtable_64.c:321:EXPORT_SYMBOL(ioremap);

WARNING: vmlinux: duplicate symbol '__ioremap' previous definition was in vmlinux
arch/powerpc/kernel/ppc_ksyms.c:117:EXPORT_SYMBOL(__ioremap);
arch/powerpc/mm/pgtable_64.c:322:EXPORT_SYMBOL(__ioremap);

WARNING: vmlinux: duplicate symbol 'iounmap' previous definition was in vmlinux
arch/powerpc/kernel/ppc_ksyms.c:118:EXPORT_SYMBOL(iounmap);
arch/powerpc/mm/pgtable_64.c:323:EXPORT_SYMBOL(iounmap);
