From 6325cb4a4ea8f4af8515b923650dd8f709694b44 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Fri, 12 Jun 2020 00:12:27 -0500 Subject: [PATCH] powerpc/numa: remove unreachable topology workqueue code Since vphn_enabled is always 0, we can remove the call to topology_schedule_update() and remove the code which becomes unreachable as a result.
