From 2dd34b488a99135ad2a529e33087ddd6a09e992a Mon Sep 17 00:00:00 2001 From: Russell King <rmk+lkml@arm.linux.org.uk> Date: Sun, 30 Oct 2005 22:42:11 +0100 Subject: [PATCH] [PATCH] kbuild: permanently fix kernel configuration include mess Include autoconf.h into every kernel compilation via the gcc command line using -imacros. This ensures that we have the kernel configuration included from the start, rather than relying on each file having #include <linux/config.h> as appropriate. History has shown that this is something which is difficult to get right. Since we now include the kernel configuration automatically, make configcheck becomes meaningless, so remove it.
