-Subject: [PATCH] net: mvneta: Fix for_each_present_cpu usage
-
-This patch convert the for_each_present in on_each_cpu, instead of
-applying on the present cpus it will be applied only on the online cpus.
-This fix a bug reported on
-http://thread.gmane.org/gmane.linux.ports.arm.kernel/468173.
-
-Using the macro on_each_cpu (instead of a for_each_* loop) also ensures
-that all the calls will be done all at once.
-
-Fixes: f86428854480 ("net: mvneta: Statically assign queues to CPUs")
