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. |

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. |

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. |
