On Arm64 Linux kernel prints log for Xen version number: [ 0.000000] Xen XEN_VERSION.XEN_SUBVERSION support found
Because the header file "xen/compile.h" is missed, XEN_VERSION and XEN_SUBVERSION are not defined, thus compiler directly uses the string "XEN_VERSION" and "XEN_SUBVERSION" in the compatible string. This patch includes the header "xen/compile.h" which defines macros for XEN_VERSION and XEN_SUBVERSION, thus Xen can pass the version number via hypervisor node.
