From 64c2a8f6d3facc2f758907c3b95686fe9e999590 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 10 May 2017 13:29:49 +0200 Subject: [PATCH] numa: add check that board supports cpu_index to node mapping Default node mapping initialization already checks that board supports cpu_index to node mapping and refuses to start if it's not supported. Do the same for explicitly provided mapping "-numa node,cpus=..."
