From 53112488bebe25c0f5f8a002470046c0fe9a6c61 Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Wed, 15 Oct 2008 22:02:37 -0700 Subject: [PATCH] alpha: introduce field 'taso' into struct linux_binprm This change is Alpha-specific. It adds field 'taso' into struct linux_binprm to remember if the application is TASO. Previously, field sh_bang was used for this purpose. Signed-off-by: Kirill A.
