  	prompt "Filter access to /dev/mem"
  	---help---
  	  This option restricts access to /dev/mem.  If this option is
  	  disabled, you allow userspace access to all memory, including
  	  kernel and userspace memory. Accidental memory access is likely
  	  to be disastrous.
  	  Memory access is required for experts who want to debug the kernel.
  
  	  If you are unsure, say Y.

  config DEBUG_STRICT_USER_COPY_CHECKS

  	def_bool n
  	prompt "Strict user copy size checks"

  	---help---
  	  Enabling this option turns a certain set of sanity checks for user
  	  copy operations into compile time warnings.
  
  	  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.
