From f5c632cfc4240a3df15b0cefed12961f4422b329 Mon Sep 17 00:00:00 2001 From: Satheesh Rajendran Date: Thu, 8 Nov 2018 10:47:56 +0530 Subject: [PATCH] powerpc/numa: Suppress "VPHN is not supported" messages [ Upstream commit 437ccdc8ce629470babdda1a7086e2f477048cbd ] When VPHN function is not supported and during cpu hotplug event, kernel prints message 'VPHN function not supported. Disabling polling...'. Currently it prints on every hotplug event, it floods dmesg when a KVM guest tries to hotplug huge number of vcpus, let's just print once and suppress further kernel prints.
