Some arch such as s390 doesn't select HAVE_IRQ_TIME_ACCOUNTING which
disables IRQ_TIME_ACCOUNTING and HAVE_SCHED_AVG_IRQ.
Checking the Ubuntu 22.04 6.8.0-86-generic config on my machine shows
CONFIG_IRQ_TIME_ACCOUNTING is disabled by default. Same is the case
with 6.14.0-34-generic config on Ubuntu 24.04.
