From 41dbc6bcd9722bba8f09256655d060af30c63d34 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 23 Jul 2015 08:22:45 +0200 Subject: KVM: x86: introduce kvm_check_has_quirk The logic of the disabled_quirks field usually results in a double negation. Wrap it in a simple function that checks the bit and negates it. Based on a patch from Xiao Guangrong.
