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. | |

13 | If unsure, say N. | |

15 | config 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. | |

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. | |

35 | Say 'N' on stable hardware. | |
