| help | |
| Add checks with low performance impact to the spinlock functions | |
| to catch memory overwrites at runtime. For more advanced | |
| spinlock debugging you should choose the DEBUG_SPINLOCK option | |
| which will detect unitialized spinlocks too. | |
| If unsure say Y here. | |

| help | |
| Select this option to enable page table locking in the TLB | |
| fault handler. This ensures that page table entries are | |
| updated consistently on SMP machines at the expense of some | |
| loss in performance. | |
