Subject: [PATCH] m68knommu: no need to set register marker on traps
Date: Fri, 18 Nov 2011 16:19:16 +1000	[thread overview]
Message-ID: <1321597156-23570-1-git-send-email-gerg@snapgear.com> (raw)

From: Greg Ungerer <gerg@uclinux.org>

Commit 61619b12078dc8b85a3d4cbfa16f650daa341bd1 ("m68k: merge mmu and
non-mmu include/asm/entry.h files") made the trap entry code basically
the same for mmu and non-mmu builds. This means we no longer need code
to mark the stack frame as "system-call" type or other in the non-mmu
trap handling entry points. This is done in the SAVE_ALL_INT macro now.
