IIRC 0 is a valid pfn. Not much of a concern since it's
used only

Currently these entries in struct page are rented by the page_pool and

Convert netmem to be a union of struct page and struct netmem. Overload
the LSB of struct netmem* to indicate that it's a net_iov, otherwise
it's a page.
Currently these entries in struct page are rented by the page_pool and
used exclusively by the net stack:
struct {
unsigned long pp_mag
