There are two ways to count file size in such a way: 1) suppose m is a poitner to the last vmcore object in vmcore_list. Then file size is (m->offset + m->size), or 2) calculate sum of size of buffers for ELF header, program headers, ELF note segments and objects in vmcore_list. Although 1) is more direct and simpler than 2), 2) seems better in that it reflects internal object structure of /proc/vmcore. Thus, this patch changes get_vmcore_size_elf{64, 32} so that it calculates size in the way of 2). As a result, both get_vmcore_size_elf{64, 32} have the same definition. Merge them as get_vmcore_size.
