From 6e17cb9c2d5efd8fcc3934e983733302b9912ff8 Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Wed, 29 Jun 2016 13:01:07 -0700 Subject: [PATCH] x86/cpufeature: Update cpufeaure macros We had a new CPUID "NCAPINT" word added, but the REQUIRED_MASK and DISABLED_MASK macros did not get updated. Update them. None of the features was needed in these masks, so there was no harm, but we should keep them updated anyway.
