   5config DEBUG_TLB_SANITY
   6        bool "Debug TLB sanity"
   7        depends on DEBUG_KERNEL
   8        help
   9          Enable this to turn on TLB sanity check on each entry to userspace.
  10          This check can spot missing TLB invalidation/wrong PTE permissions/
  11          premature page freeing.
  12
  13          If unsure, say N.

  15config LD_NO_RELAX
  16        bool "Disable linker relaxation"
  17        default n
  18        help
  19          Enable this function to disable link-time optimizations.
  20          The default linker behavior is to combine identical literal
  21          values to reduce code size and remove unnecessary overhead from
  22          assembler-generated 'longcall' sequences.
  23          Enabling this option improves the link time but increases the
  24          code size, and possibly execution time.

  26config S32C1I_SELFTEST
  27        bool "Perform S32C1I instruction self-test at boot"
  28        default y
  29        help
  30          Enable this option to test S32C1I instruction behavior at boot.
  31          Correct operation of this instruction requires some cooperation from hardware
  32          external to the processor (such as bus bridge, bus fabric, or memory controller).
  33          It is easy to make wrong hardware configuration, this test should catch it early.
  34
  35          Say 'N' on stable hardware.
