# SPDX-License-Identifier: GPL-2.0 config EARLY_PRINTK	def_bool y config DEBUG_ENTRY	bool "Debug low-level entry code"	depends on DEBUG_KERNEL	help	  This option enables sanity checks in s390 low-level entry code.	  Some of these sanity checks may slow down kernel entries and	  exits or otherwise impact performance. 	  If unsure, say N. config STRICT_MM_TYPECHECKS	bool "Strict Memory Management Type Checks"	depends on DEBUG_KERNEL	help	  Enable strict type checking for memory management types like pte_t	  and pmd_t. This generates slightly worse code and should be used	  for debug builds.
