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