+Subject: ARM: renumber bits related to _TIF_WORK_MASK
+
+From: Jens Axboe <axboe@kernel.dk>
+
+commit 191f8453fc99a537ea78b727acea739782378b0d upstream.
+
+We want to ensure that the mask related to calling do_work_pending()
+is within the first 16 bits. Move bits unrelated to that outside of
+that range, to avoid spuriously calling do_work_pending() when we don't
+need to.
+
+Cc: stable@vger.kernel.org
+Fixes: 32d59773da38 ("arm: add support for TIF_NOTIFY_SIGNAL")
