2011-12-17Remove arbitrary limits used by the zone systemRichard Braun
The zone allocator could limit the size of its zones to an arbitrary value set at zinit() time. There is no such parameter with the slab module.

2011-12-17Adjust VM initializationRichard Braun
Unlike the zone allocator, the slab code can't be fed with an initial chunk of memory.

Initialize kernel_object and vm_submap_object with _vm_object_setup() instead of _vm_object_allocate(). * vm/vm_resident.c (vm_page_bootstrap): Don't initialize kentry_data_size. * device/ds_routines.c (device_io_map_store): New variable. (device_io_map): Point to device_io_map_store. (mach_device_init): Call kmem_submap() instead of kmem_suballoc(). * ipc/ipc_init.c (ipc_kernel_map_store): New variable. (ipc_kernel_map): Point to ipc_kernel_map_store.
