From: Greg Ungerer <gerg@xxxxxxxxxxx>
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
consistentcy 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.
