Subject: [PATCH] um: Stop abusing __KERNEL__
Currently UML is abusing __KERNEL__ to distinguish between
kernel and host code (os-Linux). It is better to use a custom
define such that existing users of __KERNEL__ don't get confused.

Subject: [PATCH] um: Remove copy&paste code from init.h
As we got rid of the __KERNEL__ abuse, we can directly
include linux/compiler.h now.
This also allows gcc 5 to build UML.
