Subject: [PATCH 26/27] KVM: SVM: Expect two more candiates for exit_int_info
Date: Mon, 6 Sep 2010 17:02:01 +0200 [thread overview]
Message-ID: <1283785322-26898-27-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1283785322-26898-1-git-send-email-joerg.roedel@amd.com>
This patch adds INTR and NMI intercepts to the list of
expected intercepts with an exit_int_info set. While this
can't happen on bare metal it is architectural legal and may
happen with KVMs SVM emulation.
