   3config LIGHTWEIGHT_SPINLOCK_CHECK
   4        bool "Enable lightweight spinlock checks"
   5        depends on DEBUG_KERNEL && SMP && !DEBUG_SPINLOCK
   6        default y
   7        help
   8          Add checks with low performance impact to the spinlock functions
   9          to catch memory overwrites at runtime. For more advanced
  10          spinlock debugging you should choose the DEBUG_SPINLOCK option
  11          which will detect unitialized spinlocks too.
  12          If unsure say Y here.

  14config TLB_PTLOCK
  15        bool "Use page table locks in TLB fault handler"
  16        depends on DEBUG_KERNEL && SMP
  17        default n
  18        help
  19          Select this option to enable page table locking in the TLB
  20          fault handler. This ensures that page table entries are
  21          updated consistently on SMP machines at the expense of some
  22          loss in performance.
