Jie Deng 47e193a7bb hv: Add split-lock emulation for LOCK prefix instruction ... This patch adds the split-lock emulation. If a #AC is caused by instruction with LOCK prefix then emulate it, otherwise, inject it back as it used to be. 1. Kick other vcpus of the guest to stop execution and set the TF flag to have #DB if the guest has more than one vcpu. 2. Skip over the LOCK prefix and resume the current vcpu back to guest for execution. 3. Notify other vcpus to restart exception at the end of handling the #DB since we have completed the LOCK prefix instruction emulation.
