attilio f9319cf885 Fix the nodes allocator in architectures without direct-mapping: ... - Fix bugs in the free path where the pages were not unwired and relevant locking wasn't acquired. - Introduce the rnode_map, submap of kernel_map, where to allocate from. The reason is that, in architectures without direct-mapping, kmem_alloc*() will try to insert the newly created mapping while holding the vm_object lock introducing a LOR or lock recursion. rnode_map is however a leafly-used submap, thus there cannot be any deadlock. Notes: Size the submap in order to be, by default, around 64 MB and decrase the size of the nodes as the allocation will be much smaller (and when the compacting code in the vm_radix will be implemented this will aim for much less space to be used). However note that the size of the submap can be changed at boot time via the hw.rnode_map_scale scaling factor. - Use uma_zone_set_max() covering the size of the submap.
