Is that something you can share? I have some dual-core Intel h/w I'd
like to try this on. The xsc3 core doesn't implement all of the v6 ISA
(v5te only), but does have the standard set of ARMv6 memory barriers.
[ In theory the two xsc3 cores in this CPU aren't cache coherent but
I'd like to try it anyway. ]
