From 36d57ac4a818cb4aa3edbdf63ad2ebc31106f925 Mon Sep 17 00:00:00 2001 From: "H. J. Lu" Date: Tue, 6 Sep 2005 15:16:49 -0700 Subject: [PATCH] auxiliary vector cleanups The size of auxiliary vector is fixed at 42 in linux/sched.h. But it isn't very obvious when looking at linux/elf.h. This patch adds AT_VECTOR_SIZE so that we can change it if necessary when a new vector is added. Because of include file ordering problems, doing this necessitated the extraction of the AT_* symbols into a standalone header file.
