[Qemu-devel] [PATCH] target-i386:kvm_get/put_vcpu_events don't handle sipi_vector

[Peng Hao <peng.hao2@zte.com.cn>]

qemu call kvm_get_vcpu_events, and kernel return sipi_vector always 0,
never valid when reporting to user space. But qemu call kvm_put_vcpu_events
will make sipi_vector in kernel be 0. This will accidently modify sipi_vector
when sipi_vector in kernel is not 0.
