Most of the users of page_set_flags offset (page, page + len) as the end points. One might consider this an error, since the other users do supply an endpoint as the last byte of the region.
However, the first thing that page_set_flags does is round end UP to the start of the next page. Which means computing page + len - 1 is in the end pointless. Therefore, accept this usage and do not assert when given the exact size of the vm as the endpoint.
