Hi all, this patch series by Wei Liu implements a simple Xen APIC module and use it to deliver MSI/MSIX for Xen HVM guests. The second version of this series includes the "or later" copyright clause for xen_apic.c and a fix to the return value of xen_apic_mem_read (thanks Peter for finding it out).
