From 479badc364b52774d77264aaf81f4d4b375a4a97 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Wed, 2 Nov 2011 15:44:42 +1000 Subject: [PATCH] m68k: make fp register stores consistent for m68k and ColdFire There is no reason we can't make the saved fp registers the same for all m68k types and ColdFire. There is a little wasted space, but the code consistency and cleanliness is a big win. sigcontext.h is an exported header, but currently there is no in-mainline users of the !__uClinux__ and __mcoldfire__ case that this change effects. Even better this change actually makes this structure consistent with the out-of-mainline ColdFire/MMU code.
