Jie Deng 977e862192 hv: Add split-lock emulation for xchg ... xchg may also cause the #AC for split-lock check. This patch adds this emulation. 1. Kick other vcpus of the guest to stop execution if the guest has more than one vcpu. 2. Emulate the xchg instruction. 3. Notify other vcpus (if any) to restart execution.
