[PATCH] headers_check: don't expose PFN stuff to userspace in <asm-i386/setup.h>
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.
