powerpc: hash_page_sync should only be used on SMP & STD_MMU_32
Clean up the ifdefs so we only use hash_page_sync if we have CONFIG_SMP && CONFIG_PPC_STD_MMU_32. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
