config LIGHTWEIGHT_SPINLOCK_CHECK
bool "Enable lightweight spinlock checks"
depends on SMP && !DEBUG_SPINLOCK
default y
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.
config TLB_PTLOCK
bool "Use page table locks in TLB fault handler"
depends on SMP
default n
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.
