13 Enables the display of the minimum amount of free stack which each
14 task has ever had available in the sysrq-T and sysrq-P debug output.

40 Enabling this option turns a certain set of sanity checks for user
41 copy operations into compile time failures.
43 The copy_from_user() etc checks are there to help test if there
44 are sufficient security checks on the length argument of
45 the copy operation, by having gcc prove that the argument is
48 If unsure, or if you run an older (pre 4.4) gcc, say N.
