From 0d96fb20b7ed757fc936bb35e26c22251a75b734 Mon Sep 17 00:00:00 2001 From: Richard Hacker Date: Thu, 28 Feb 2008 09:40:58 +0100 Subject: kbuild: Add new Kbuild variable KBUILD_EXTRA_SYMBOLS This patch adds a new (Kbuild) Makefile variable KBUILD_EXTRA_SYMBOLS. The space separated list of file names assigned to KBUILD_EXTRA_SYMBOLS is used when calling scripts/mod/modpost during stage 2 of the Kbuild process for non-kernel-tree modules.
