[Qemu-devel] [PATCH 4/7] KVM regsync: Add register level parameter to kvm_cpu_synchronize_state |
Date: |
Fri, 21 Dec 2012 08:56:09 -0500 |
From: "Jason J. Herne" <address@hidden>
kvm_cpu_synchronize_state is updated to take/propagate the register level
parameter. All callers are modified to specify the runtime state.
