From: Heiko Carstens Date: Wed, 5 Aug 2020 12:50:41 +0000 (+0200) Subject: s390/time: remove select CLOCKSOURCE_VALIDATE_LAST_CYCLE again X-Git-Tag: v5.9-rc1~39^2~1 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=12bbf0962afa903321f28c454d7b667199ae55da;p=thirdparty%2Fkernel%2Flinux.git 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").
