Subject: [PATCH 3/3] m68k: use same start_thread() on MMU and no-MMU
Date: Fri, 22 Jul 2016 10:40:09 +1000	[thread overview]
Message-ID: <1469148009-25426-4-git-send-email-gerg@linux-m68k.org> (raw)
In-Reply-To: <1469148009-25426-1-git-send-email-gerg@linux-m68k.org>

The MMU and no-MMU versions of start_thread() are now identical, so use
the same common code for both.
