Thanks, I've added the following patch to linux-pm/linux-next, which should
fix this problem (Tejun, if that's not the right thing to do, please let me
know).

Subject: Freezer: Make dmatest_func() use set_freezable()

According to the commit cd3bc8fbc2d55ae0918184fb34992054dc4eb710
(freezer: kill unused set_freezable_with_signal()) changelog,
it should be sufficient to use set_freezable() instead of
set_freezable_with_signal(), which has been removed, in
dmatest_func(), so do that and fix a build issue.
