   9           If you say Y here then read-write lock processing will count how many
  10           times it has tried to get the lock and issue an error message after
  11           too many attempts.  If you suspect a rwlock problem or a kernel
  12           hacker asks for this option then say Y.  Otherwise say N.

  18          Mark the kernel read-only data as write-protected in the pagetables,
  19          in order to catch accidental (and incorrect) writes to such const
  20          data. This option may have a slight performance impact because a
  21          portion of the kernel code won't be covered by a TLB anymore.
  22          If in doubt, say "N".
