#     powerpc: Always enable queued spinlocks for 64s, disable for others
#     
#     Queued spinlocks have shown to have good performance and fairness
#     properties even on smaller (2 socket) POWER systems. This selects them
#     automatically for 64s. For other platforms they are de-selected, the
#     standard spinlock is far simpler and smaller code, and single chips
#     with a handful of cores is unlikely to show any improvement.
#     
#     CONFIG_EXPERT still allows this to be changed, e.g., to help debug
#     performance or correctness issues.
