   7           Enable this to turn on TLB sanity check on each entry to userspace.
   8           This check can spot missing TLB invalidation/wrong PTE permissions/
   9           premature page freeing.

  11           If unsure, say N.

  17           Enable this function to disable link-time optimizations.
  18           The default linker behavior is to combine identical literal
  19           values to reduce code size and remove unnecessary overhead from
  20           assembler-generated 'longcall' sequences.
  21           Enabling this option improves the link time but increases the
  22           code size, and possibly execution time.

  28           Enable this option to test S32C1I instruction behavior at boot.
  29           Correct operation of this instruction requires some cooperation from hardware
  30           external to the processor (such as bus bridge, bus fabric, or memory controller).
  31           It is easy to make wrong hardware configuration, this test should catch it early.
  32
  33           Say 'N' on stable hardware.

  38         help
  39           This option allows you to set the stack depth that the kernel
  40           prints in stack traces.
