From 2b3c5cbc0d814437fe4d70cc11ed60550b95b29f Mon Sep 17 00:00:00 2001 From: Zhang Xiantao Date: Wed, 5 Dec 2012 01:55:15 +0800 Subject: kvm: don't use bit24 for detecting address-specific invalidation capability Bit24 in VMX_EPT_VPID_CAP_MASI is not used for address-specific invalidation capability reporting, so remove it from KVM to avoid conflicts in future.
