to the private VM types are including vm_types.h now. * Removed vm_page, vm_area, vm_cache, and vm_address_space typedefs; it's cleaner this way, and the actual types are only used in C++ files now, anyway. * And that caused changes in many files... * Made commpage.h self-containing. * Minor cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22329 a95241bf-73f2-0310-859d-f6bbb57e9c96
