X-Git-Tag: accepted/tizen/unified/20230118.172025~6566^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c7483d823ee0da31e42d32e51a752f667a059735;p=platform%2Fkernel%2Flinux-rpi.git Documentation: Replace deprecated CPU-hotplug functions. The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock(). Update the documentation accordingly.
