* vm_page::offset is now called cache_offset and is now an uint32 instead of off_t; 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 2005-12-21 15:38:31 +03:00			`#define PAGE_SHIFT 12`
