From: Russell King Date: Sun, 30 Oct 2005 21:42:11 +0000 (+0100) Subject: [PATCH] kbuild: permanently fix kernel configuration include mess X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2dd34b488a99135ad2a529e33087ddd6a09e992a;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [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 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.
