Subject: FRV: possibly bad unsigned comparison in show_backtrace()

In arch/frv/kernel/traps.c, show_backtrace(), if sp is 0
then the dump does not succeed because stop was set to 0
and unaltered when we reach the unsigned comparison:

 while (tos < stop) {...}

The naming stop may on the other hand suggest that this
is desired, is it?
