Postcopy live-migration features relies on userfaultfd, which was only introduced in kernel v4.3. This patch introduces a new define to allow building vhost library on kernels not supporting userfaultfd. With legacy build system, user has to explicitly set CONFIG_RTE_LIBRTE_VHOST_POSTCOPY to 'y'. With Meson build system, RTE_LIBRTE_VHOST_POSTCOPY gets automatically defined if userfaultfd kernel header is present.
