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.
