kmap_pte and kmap_prot export symbol:
    when CONFIG_HIGHMEM is true in kernel/ksyms.c on redhat 7.3 kerenel.
    when CONFIG_PM_MEMORY is true in arch/i386/kernel/i386_ksyms.c on SCore patch.

empty_zero_page export symbol:
    always true in arch/i386/kernel/i386_ksyms.c on redhat 7.3 kerenel.
    when CONFIG_PM_MEMORY is true in  kernel/ksyms.c on SCore patch.


Please delete these lines:
  In kernel/ksyms.c
     EXPORT_SYMBOL(empty_zero_page);
  in arch/i386/kernel/i386_ksyms.c
     EXPORT_SYMBOL(kmap_pte);
     EXPORT_SYMBOL(kmap_prot);
