We've found recently that it's not very hard to bump into the limit
of the number of owner_ids that the ACPI subsystem can provide.
[...] Doubling the limit to 64 is a sufficient short term fix
and a fairly trivial patch, maybe even something that could go in before
2.6.15. Len, could we do something like the below patch to give us a
little more reasonable limit? We could switch to a bitmap too, but
given how close the next kernel is to release this is less impact.
Thanks,
Alex

Shouldn't this be 1ULL if you intend it to be 64 bit wide on a
32 bit arch?
