From 1be2edb25c72c3fe1bf955694c5521b035fcb276 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 5 Apr 2023 16:34:52 +0200 Subject: [PATCH] proc/stat: remove arch_idle_time() The last (only) architecture specific arch_idle_time() implementation was removed with commit be76ea614460 ("s390/idle: remove arch_cpu_idle_time() and corresponding code"). Therefore remove the now dead code in fs/proc/stat.c as well.
