From 230ec93909f00678401cb2d63b8b95f1dea68e40 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Fri, 4 Sep 2015 15:45:06 -0700 Subject: smpboot: allow passing the cpumask on per-cpu thread registration It makes the registration cheaper and simpler for the smpboot per-cpu kthread users that don't need to always update the cpumask after threads creation.
