* Pulled the physical page mapping functions out of vm_translation_map into a new interface VMPhysicalPageMapper. * Renamed vm_translation_map to VMTranslationMap and made it a proper C++ class. The functions in the operations vector have become methods. * Added class GenericVMPhysicalPageMapper implementing VMPhysicalPageMapper as far as possible (without actually writing new code). * Adjusted the x86 and the PPC specifics accordingly (untested for the latter). For the other architectures the build is, I'm afraid, seriously broken. The next steps will modify and extend the VMTranslationMap interface, so that it will be possible to fix the bugs in vm_unmap_page[s]() and employ architecture specific optimizations. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35066 a95241bf-73f2-0310-859d-f6bbb57e9c96
