Below a patch to preallocate memory when doing resize of trie (inflate halve)
If preallocations fails it just skips the resize of this tnode for this time.
The oops we got when killing bgpd (with full routing) is now gone.
Patrick memory patch is also used.

Inflating a node a couple of times makes it exceed the 128k kmalloc limit.
Use __get_free_pages for allocations > PAGE_SIZE, as in fib_hash.

This should help up the insertion... but the resize is more crucial.
and complex and needs some thinking.
