This API allows callers to enumerate all known pages, including any direct map & kernel map virtual addresses, physical addresses, size, offset into the core, & protection configured. For architectures that support direct map addresses, also generate pages for any direct map only addresses that are not associated with kernel map addresses. Fix page size portability issue left behind from previous kvm page table lookup interface. Reviewed by: jhb Sponsored by: Backtrace I/O Differential Revision: https://reviews.freebsd.org/D12279
