menu "Kernel hacking" source "lib/Kconfig.debug" config DEBUG_TLB_SANITY	bool "Debug TLB sanity"	depends on DEBUG_KERNEL	help	  Enable this to turn on TLB sanity check on each entry to userspace.	  This check can spot missing TLB invalidation/wrong PTE permissions/	  premature page freeing. 	  If unsure, say N. config LD_NO_RELAX	bool "Disable linker relaxation"	default n	help	  Enable this function to disable link-time optimizations.	  The default linker behavior is to combine identical literal	  values to reduce code size and remove unnecessary overhead from	  assembler-generated 'longcall' sequences.	  Enabling this option improves the link time but increases the	  code size, and possibly execution time. config S32C1I_SELFTEST	bool "Perform S32C1I instruction self-test at boot"	default y	help	  Enable this option to test S32C1I instruction behavior at boot.	  Correct operation of this instruction requires some cooperation from hardware	  external to the processor (such as bus bridge, bus fabric, or memory controller).	  It is easy to make wrong hardware configuration, this test should catch it early. 	  Say 'N' on stable hardware. endmenu
