From df386f15b2fbe51863d0f076d5939d5cbdb36f0d Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Thu, 6 Oct 2022 20:56:35 +1000 Subject: [PATCH] s390: remove the last remnants of cputime_t cputime_t was a core kernel type, removed by commits ed5c8c854f2b..b672592f0221. As explained in commit b672592f0221 ("sched/cputime: Remove generic asm headers"), the final cleanup is for the arch to provide cputime_to_nsec[s](). Commit e53051e757d6 ("s390/cputime: provide archicture specific cputime_to_nsecs") did that, but just didn't remove the then-unused cputime_to_usecs() and associated remnants.
