	bool "Debug TLB sanity"
	depends on DEBUG_KERNEL && MMU
	  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 y
	  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
	  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.
