v4.4 (arm:allmodconfig):

There is also a qemu runtime failure with omap2plus_defconfig in v4.4.

I am also seeing this in 4.4.8 on an DM3730.  I didn't see it in
4.4.3.  I can also help bisect if it helps.

I ended up bisecting it [1]. The problem is seen in 4.4.7 and 4.4.8
(I originally thought 4.4.6 was affected as well, but it was introduced
in 4.4.7). It will be fixed in 4.4.9; the necessary patches are already
in the queue.
