this saves 4 bytes per page. To compensate the loss of bytes, the offset is now stored in page size units, that's enough to address 2^44 or 16 TB (which is now the maximal supported file size!). * Renamed vm_page::ppn to physical_page_number. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15637 a95241bf-73f2-0310-859d-f6bbb57e9c96
