Hi Jeff,
ARM has it:

Did you verify that it works?
No. Olivier would be able to answer though.
If you can test ULE on UP arm/powerpc I'd appreciate it. Then we could
add them to the set of supported architectures in ULE.
Does arm support SMP? It looks like it does not?
Don't think so.
For UP it doesn't need to wait for blocked lock to clear but it does need
to set td_lock. On UP there are no special synchronization requirements so
it can happen as the very first instruction in cpu_switch.
OK, I'll give it a whirl.

Peter.
Thanks,
Jeff
