Subject: [PATCH] m68k: use of 64 div instruction is chip specific
Date: Fri, 21 Oct 2011 17:08:05 +1000 [thread overview]
Message-ID: <1319180885-11145-1-git-send-email-gerg@snapgear.com> (raw)
From: Greg Ungerer <gerg@uclinux.org>
The use of the 64 div instruction should not be based on whether we
are running MMU enabled or not. It is chip specific. The original
68000 family and the ColdFire CPU family do not support it, the
other 680x0 CPU varients do. So make the conditional check based on
that, not CONFIG_MMU.
