- If either an alloc or release function is provided, make sure both are provided, otherwise panic, as this is a fatal error. - If using the default allocator, default the pool pagesz to PAGE_SIZE, since that is the granularity of the default allocator's mechanism. - In the default allocator, use new functions: uvm_km_alloc_poolpage()/uvm_km_free_poolpage(), or kmem_alloc_poolpage()/kmem_free_poolpage() rather than doing it here. These functions may use pmap hooks to provide alternate methods of mapping pool pages.
