Subject: [Qemu-devel] [PATCH] kvm: x86: Drop redundant apic base and tpr update from kvm_get_sregs
Date: Wed, 26 Oct 2011 13:09:45 +0200 [thread overview]
Message-ID: <4EA7EA79.1090503@siemens.com> (raw)
The latter was already commented out, the former is redundant as well.
We always get the latest changes after return from the guest via
kvm_arch_post_run.
