hi all,

i have two questions regarding the page tables of domains.

1. get_pfn_type_batch() seems to have a single-page limit. ie, trying to
get pfn types for an array larger than a page fails. why the restriction?

2. L1 page tables seem to contain mfns of not only L2 pages, but "normal"
pages as well. can anyone explain this?

thanks,
-A.
