From 5bd9dd450173bc1464e8218e717d218075b9f1a4 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Wed, 9 May 2012 16:03:06 +1000 Subject: [PATCH] m68k: use some direct calls to ret_from_exception in entry code The ret_from_excption code is referenced by its function name, or by a label set at the start of its code. The non-MMU code can share some of this code if we make direct calls to ret_from_exception instead of the associated label. The effected function paths are: buserr, trap and ret_from_fork. So change these to branch directly to ret_from_exception.
