While investigating the 2.4 memory corruption problem fixed by the patch
previously posted, it was noticed that the 2.6 version of get_kcore_size()
inappropriately uses sizeof(struct memelfnote) in its calculation of the
/proc/kcore ELF header size.  What is actually stored in the header is an
"elf_note" structure plus the 4 ASCII chars "CORE".

It just so happens that on 32-bit arches, both calculations result in the
same value (16).  But on 64-bit arches, the allocated size (24) is larger
than necessary (16).  This does not result in any possible data corruption,
but it might be nice to correct this "conceptual" error.
