From c6bd18011ff8ea23473a1f4c6d934f761879081d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= Date: Sat, 5 Aug 2017 00:12:48 +0200 Subject: [PATCH] KVM: x86: X86_FEATURE_NRIPS is not scattered anymore MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit bit(X86_FEATURE_NRIPS) is 3 since 2ccd71f1b278 ("x86/cpufeature: Move some of the scattered feature bits to x86_capability"), so we can simplify the code.
