From 5edc2a5123a7c3d9bcb19ffcf3b91e8d6c246092 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 15 Oct 2008 22:04:16 -0700 Subject: [PATCH] binfmt_elf_fdpic: wire up AT_EXECFD, AT_EXECFN, AT_SECURE These auxvec entries are the only ones left unhandled out of the current base implementation. This syncs up binfmt_elf_fdpic with linux/auxvec.h and current binfmt_elf.
