Message-Id: <20230405143452.2677172-1-hca@linux.ibm.com>

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.
