vm.h was not used anywhere. Introduced new arch_vm.h ("public" arch headers have the arch_ prefix). git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10384 a95241bf-73f2-0310-859d-f6bbb57e9c96 2004-12-10 21:43:26 +03:00			`/*`

* 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`
