        With CONFIG_SPARSEMEM on xen x86_64, you get an oops in mem_init where
it references mem_map; mem_map is only initialized with CONFIG_FLATMEM.

        Suggest a Kconfig change like the one attached?

Perhaps better to forcibly disable CONFIG_NUMA if CONFIG_XEN isenabled? We can't (yet) pick up NUMA info from Xen anyway, and itprobably enables a bunch of code that hasn't been much tested on Xen.
