From ecba97d4aacf4e80c56eb73e39af0369cb8539a4 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Wed, 28 Sep 2005 22:27:23 +0100 Subject: [PATCH] uml makefiles sanitized UML makefiles sanitized: - number of generated headers reduced to 2 (from user-offsets.c and kernel-offsets.c resp.). The rest is made constant and simply includes those two. - mk_... helpers are gone now that we don't need to generate these headers - arch/um/include2 removed since everything under arch/um/include/sysdep is constant now and symlink can point straight to source tree. - dependencies seriously simplified.
