Subject: [PATCH 3.18 04/36] um: Remove copy&paste code from init.h

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Richard Weinberger <richard@....at>

commit 30b11ee9ae23d78de66b9ae315880af17a64ba83 upstream.

As we got rid of the __KERNEL__ abuse, we can directly
include linux/compiler.h now.
This also allows gcc 5 to build UML.
