[Xen-devel] virtual frame_table?

On ia64 we had a virtual frame_table to allow for better handling of
sparse memory configs.  Has x86 considered anything similar?  I see that
init_frametable() is currently allocating 32bytes per page for
everything up to max_page.  This can consume a pretty significant chunk
of memory if nodes are discontiguous.  Anyone motivated to fix it?
Thanks,

Alex
