From: Ernie Petrides 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.
