Message-ID: <20071011190923.GA23595@havoc.gtf.org>

Subject: [git patch] DMI const-ification
This has been in -mm for a while, has been ack'd by many relevant
parties, and has not received any nak's.
I was holding off sending this until the x86 merge, but I suppose git
can handle all the file movement and stuff. If you just wanna drop this
and wait for me to rediff+resend after the x86 merge, that's cool.
Please pull from 'dmi-const' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/misc-2.6.git dmi-const
to receive the following updates:
