-    MIPS: CM, CPC: Ensure core-other GCRs reflect the correct core
-    
-    Ensure the update to which core the core-other GCR regions reflect has
-    taken place before any core-other GCRs are accessed by placing a memory
-    barrier (sync instruction) between the write to the core-other registers
-    and any such GCR accesses.
