[PATCH] Require mmap handler for a.out executables
Files supported by fs/proc/base.c, i.e. /proc/<pid>/*, are not capable of meeting the validity checks in ELF load_elf_*() handling because they have no mmap handler which is required by ELF. In order to stop a.out executables being used as part of an exploit attack against /proc-related vulnerabilities, we make a.out executables depend on ->mmap() existing.
