I expanded this a bit to include:
(XEN) Initial low memory virq threshold set at 0x4000 pages.
(XEN) NODE0 start=0x0 pages=579306, max_page=0xc0000
(XEN) NODE0: #0 #1 #2 #3 #4 #5 #6 #7 (total=8)
(XEN) NODE0 start=0x0, per_cpu=72413, rem=2, end=0x8d6ea
^^^^^^^^ that is the end of memory, but
0xb98ae > 0x8d6ae.
end = min(node_start_pfn(i) + node_spanned_pages(i), max_page);
0 0x8D6EA 0xc0000
Oh:
/* XXX: implement NUMA support */
#define node_spanned_pages(nid) (total_pages)
<facepalm>
