From: Jan Glauber <[email protected]>
Remove useless s390 define from hangcheck-timer, remove wrong definition
of a TOD second and other s390 ifdefs. Use monotonic_clock instead.
Add hangcheck-timer option, copied from drivers/char/Kconfig.
This is ugly but unless we have a big Kconfig cleanup we cannot
include drivers/char/Kconfig...
