+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.
