From a37f6aeeeabd2aefa55f4101454510bec98b20ca Mon Sep 17 00:00:00 2001 From: Christian Dietrich Date: Wed, 4 Aug 2010 14:42:19 +0200 Subject: [PATCH] arch/m68knommu: Removing dead M68KFPU_EMU config option CONFIG_M68KFPU_EMU doesn't exist in Kconfig, therefore removing all references to it from the source. This Flags seems to exist only on m68k with mmu, and this dead blocks are copy paste.
