File runtime-bump-MaxGomaxprocs.patch of Package go1.8
From b75347d41a3771f8acab13a4dbd607254fdc5054 Mon Sep 17 00:00:00 2001 From: Aleksa Sarai <asarai@suse.de> Date: Tue, 14 Mar 2017 00:14:38 +1100 Subject: [PATCH] runtime: bump _MaxGomaxprocs to (1 << 10) This is required so that we can run k8s and Docker on machines with quite large numbers of CPUs. (1 << 10) should be big enough /for now/. SUSE: Don't upstream this.
