ARM: renumber bits related to _TIF_WORK_MASK

Browse source

commit 191f8453fc 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.
