From 80c00ba942ee39c9a95c06959223560400bbb86e Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Wed, 28 Jul 2010 19:11:27 +0200 Subject: kbuild: allow assignment to {A,C}FLAGS_KERNEL on the command line It is now possible to assign options to AS and CC on the command line - which is only used for built-in code. {A,C}FLAGS_KERNEL was used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC without overriding the original value. Introduce a new set of variables KBUILD_{A,C}FLAGS_KERNEL that is used by arch specific files and free up {A,C}FLAGS_KERNEL so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated.
