Yi Wang	ccb604e1e1	vmm: add cpu segment note for coredump ... The crash tool use a special note segment which named 'QEMU' to analyze kaslr info and so on. If we don't add the 'QEMU' note segment, crash tool can't find linux version to move on. For now, the most convenient way is to add 'QEMU' note segment to make crash tool happy.
