Subject: [PATCH 2/5] KVM: SVM: don't copy exit_int_info on nested vmrun
Date: Wed, 16 Sep 2009 15:24:16 +0200 [thread overview]
Message-ID: <1253107459-8967-3-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1253107459-8967-1-git-send-email-joerg.roedel@amd.com>
The exit_int_info field is only written by the hardware and
never read. So it does not need to be copied on a vmrun
emulation.
