Subject: [PATCH] m68k: Revive _TIF_* masks
Date:   Wed, 26 Aug 2020 14:29:23 +0200
Message-Id: <20200826122923.22821-1-geert@linux-m68k.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

While the core m68k code does not use the _TIF_* masks anymore, there
exists generic code that relies on their presence.  Fortunately none of
that code is used on m68k, currently.

Re-add the various _TIF_* masks, which were removed in commit
cddafa3500fde4a0 ("m68k/m68knommu: merge MMU and non-MMU
thread_info.h"), to avoid future nasty surprises.
