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.
