From d2922422c48df93f3edff7d872ee4f3191fefb08 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Dirk=20M=C3=BCller?= Date: Thu, 1 Oct 2015 13:43:42 +0200 Subject: [PATCH] Use WARN_ON_ONCE for missing X86_FEATURE_NRIPS The cpu feature flags are not ever going to change, so warning everytime can cause a lot of kernel log spam (in our case more than 10GB/hour). The warning seems to only occur when nested virtualization is enabled, so it's probably triggered by a KVM bug. This is a sensible and safe change anyway, and the KVM bug fix might not be suitable for stable releases anyway.
