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".
