=== Non-idempotent memory handling

An implementation may have a requirement to issue a load/store pair instruction to non-idempotent memory.

If an implementation of a hart does not support Zilsd instructions to non-idempotent memories, the hart may use an idempotency PMA to detect it and take a load or store access fault exception in order to avoid unpredictable results.

Software should only use these instructions on non-idempotent memory regions when software can tolerate the required memory accesses being issued repeatedly in the case that they cause exceptions.
