From e09b41010ba33a20a87472ee821fa407a5b8da36 Mon Sep 17 00:00:00 2001
From: José Pekkarinen <jose.pekkarinen@nokia.com>
Date: Mon, 11 Apr 2016 10:41:07 +0300
Subject: These changes are the raw update to linux-4.4.6-rt14. Kernel sources
 are taken from kernel.org, and rt patch from the rt wiki download page.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

During the rebasing, the following patch collided:

Force tick interrupt and get rid of softirq magic(I70131fb85).

Collisions have been removed because its logic was found on the
source already.
