- 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.
