s390/time: remove select CLOCKSOURCE_VALIDATE_LAST_CYCLE again
Sven Schnelle reported that setting CLOCKSOURCE_VALIDATE_LAST_CYCLE doesn't make sense: even if our tod clock overflows delta calculation (now - last) with unsigned 64 bit values will still be correct. Therefore revert commit 555701a714f7 ("s390/time: select CLOCKSOURCE_VALIDATE_LAST_CYCLE"). Fixes: 555701a714f7 ("s390/time: select CLOCKSOURCE_VALIDATE_LAST_CYCLE") Reported-by: Sven Schnelle <svens@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
