- the above file now also exports a function to finally complete the kernel's address space translation map after semaphores became available (was just not done before) - renamed some functions, especially the *_init2() functions are now called like *_init_post_area() to indicate they are called after the area functionality became available - removed the _struct suffix from certain structures - fixed some return types - added prototype for vm_free_unused_boot_loader_range() to be called by arch code. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9423 a95241bf-73f2-0310-859d-f6bbb57e9c96
