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

config DEBUG_STRICT_USER_COPY_CHECKS
	bool "Strict copy size checks"
	depends on DEBUG_KERNEL && !TRACE_BRANCH_PROFILING
	---help---
	  Enabling this option turns a certain set of sanity checks for user
	  copy operations into compile time failures.

	  The copy_from_user() etc checks are there to help test if there
	  are sufficient security checks on the length argument of
	  the copy operation, by having gcc prove that the argument is
	  within bounds.

	  If unsure, or if you run an older (pre 4.4) gcc, say N.
