------------------------------------------------------
Subject: headers_check: don't expose PFN stuff to userspace in <asm-i386/setup.h>
From: David Woodhouse <dwmw2@xxxxxxxxxxxxx>
The header file <linux/pfn.h> doesn't exist in userspace and probably
shouldn't -- but it's used unconditionally in <asm-i386/setup.h>. Protect it
with #ifdef __KERNEL__ and move setup.h from $(header-y) to $(unifdef-y) in
Kbuild accordingly.
