Subject: [PATCH] x86,kmemcheck: Use KERN_WARNING for error reporting

From: Pekka Enberg <penberg@...helsinki.fi>

As suggested by Vegard Nossum, use KERN_WARNING for error reporting to make
sure kmemcheck reports end up in syslog.

Vegard, how do you want to merge this? Andrew? Ingo? I can also pick it
up in my tree if you ACK it.
