[patch 10/17] use WARN() in arch/x86/mm/pageattr.c

[Arjan van de Ven <arjan@infradead.org>]

From: Arjan van de Ven <arjan@linux.intel.com>
Subject: Use WARN instead of printk+WARN_ON in x86/mm/pageattr

Use WARN() instead of a printk+WARN_ON() pair; this way the message
becomes part of the warning section for better reporting/collection.
