Subject: [PATCH 5/9] KVM: MMU: split reset_rsvds_bits_mask_ept
Date: Tue, 4 Aug 2015 18:59:17 +0800 [thread overview]
Message-ID: <1438685961-8107-6-git-send-email-guangrong.xiao@linux.intel.com> (raw)
In-Reply-To: <1438685961-8107-1-git-send-email-guangrong.xiao@linux.intel.com>
Since shdow ept page tables and intel nested guest page tables have the
same format, split reset_rsvds_bits_mask_ept so that the logic can be
reused by later patches which check reserved bits on sptes
