program exception emulates mfspr PVR

[Frank Rowand]

Why did emulate_instruction() get added into traps.c to emulate the
mfspr PVR instruction?  What user space application is using this
instruction?

And why add this extra cruft?  The information is already available to
user applications (one example, /proc/cpuinfo reports the cpu and revision).


Thanks,

Frank
