 CVS commit: src/sys/arch/m68k/m68k
 
 Module Name:    src
 Committed By:   nat

 Modified Files:
         src/sys/arch/m68k/m68k: switch_subr.s
 
         Log Message:
         Sprinkle nop.
 
         This is the kernel part of addressing the issue with fpu emulation on 
 	lc040 cpus.
 
         The idea is that we might be switch from or to an f-line (MMU/FPU 
 	Trap) instruction so prepend a nop to flush the caches.
 
         Addresses part of PR/13078.
 
         The second part to this (patch to binutils/gas) has been submitted		
 	upstream
         and will be fixed when this part is reviewed and included in our local 
 	copy of binutils or (hopefully) in a later version of binutils from 
 	upstream.
