I've changed it to:
ARM: use a function table for determining instruction interpreter actions
Make the instruction interpreter call back to semantic action functions through a function pointer array provided by the invoker. The interpreter decodes the instructions into groups and uses the group number to index into the supplied array. kprobes and uprobes code will each supply their own array of functions.

Fixed for next version (as described in previous email).
