Or even better:
1. remove enter_kdebug() from L.238
2. enter_kdebug() if the exception was _not_ caused in the user area:

221     if (space->is_user_area(addr))
222     {
		[...]
240     }
241 	else
242	  enter_kdebug("invalid opcode");

3. remaining code is left unchanged

By this, an exception-IPC would be sent iff the faulting opcode a) is
not the sequence "lock; nop;" and b) it was executed in the user area.
Invalid opcodes outside the user area would cause enter_kdebug() to be
executed.
Would make more sense to me...
