The patch titled
Subject: kbuild: decouple build from userspace headers
has been removed from the -mm tree. Its filename was
decouple-build-from-userspace-headers.patch
This patch was dropped because it had testing failures
------------------------------------------------------
From: Alexey Dobriyan <adobriyan@gmail.com>
Subject: kbuild: decouple build from userspace headers
First, userspace headers can be under incompatible license.
Second, kernel doesn't require userspace to operate and should not
require anything from userspace to be built other than compiler.
We would use -ffreestanding too if not builtin function shenanigans.
To decouple:
* ship minimal stdarg.h as <linux/stdarg.h>,
1 type, 4 macros
GPL 2 version of <stdarg.h> can be extracted from
http://archive.debian.org/debian/pool/main/g/gcc-4.2/gcc-4.2_4.2.4.orig.tar.gz
* delete "-isystem" from command line arguments,
this is what enables header leakage
* fixup/delete include directives where necessary.
[adobriyan@gmail.com: allow to find SIMD headers where necessary]
