o.k. jiri, here is what I came up with, after re-reading and looking at
other in the kernel(below).

Subject: [PATCH]kernel.h Fix #warning message according to the GCC
preprocessor docs.

received this #warning from a simple printk program and noticed the web
address is not showing up:
gcc printk.c -o printk
In file included from printk.c:3:
include/linux/kernel.h:733:2: warning: #warning Attempt to use kernel
headers from user space, see http:

after the changes the warning should just say:
#warning Attempt to use kernel headers from user space!

now I'm wondering if there should be a lead to the documentation with
this web address(seems grep is not finding anything that I might be able
to use).or just leave as is, and let people connect-the-dots!!

let me know..
