9 config DEBUG_STACK_USAGE
10 bool "Enable stack utilization instrumentation"
11 depends on DEBUG_KERNEL
13 Enables the display of the minimum amount of free stack which each
14 task has ever had available in the sysrq-T and sysrq-P debug output.
16 This option will slow down process creation somewhat.
19 bool "D-cache flush debugging"

26 bool "Debug page memory allocations"
27 depends on DEBUG_KERNEL && !HIBERNATION
28 depends on ARCH_SUPPORTS_DEBUG_PAGEALLOC
30 Unmap pages from the kernel linear mapping after free_pages().
31 This results in a large slowdown, but helps to find certain types
32 of memory corruptions.
