10 This option enables sanity checks in s390 low-level entry code.
11 Some of these sanity checks may slow down kernel entries and
12 exits or otherwise impact performance.

20 Enable strict type checking for memory management types like pte_t
21 and pmd_t. This generates slightly worse code and should be used
22 for debug builds.

30 This option provides a debugging facility to inject certain artificial events
31 and instruction responses to the CIO layer of Linux kernel. The newly created
32 debugfs user-interfaces will be at /sys/kernel/debug/s390/cio/*
