+What:  a.out interpreter support for ELF executables
+When:  2.6.25
+Files: fs/binfmt_elf.c
+Why:   Using a.out interpreters for ELF executables was a feature for
+       transition from a.out to ELF. But now it is unlikely to be still
+       needed anymore and removing it would simplify the hairy ELF
+       loader code.
