[PATCH] proc/stat: remove arch_idle_time()

From: Heiko Carstens
Date: Wed Apr 05 2023 - 10:35:09 EST


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.
