From 9b13a93df267af681a66a6a738bf1af10102da7d Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Wed, 18 Jun 2014 00:06:23 +0200 Subject: x86, cpufeature: Convert more "features" to bugs X86_FEATURE_FXSAVE_LEAK, X86_FEATURE_11AP and X86_FEATURE_CLFLUSH_MONITOR are not really features but synthetic bits we use for applying different bug workarounds. Call them what they really are, and make sure they get the proper cross-CPU behavior (OR rather than AND).
