The only solution I can think of is moving the bitmap elsewhere, above 4GB in
this case:
figure the size of bitmap, DIRECT map space, allocate the map,
mark it reserved in the RAM map, and should work!
I'd have add a loop around init_boot_allocator() in __start_xen()
iterating thru the RAM map again, and finding space above 16M.
Am I on the right track?
A 512GB system still needs only 16MB of allocator bitmap. There's no need
for a complicated solution, moving it above 4GB or anything.
I've actually broken xen-unstable and forgotten to account for the allocator
bitmap overhead when I relocate Xen. I will fix that, and properly account
for the bitmap overhead rather than add a fixed overhead (which is probably
what breaks you on 3.1.4). I'll let you know when that's done.

ok, that sounds better solution. Let me know. Next on my list is customer
unable to boot 256GB PV guest, stay tuned.
Thanks,
